If I only get three hours of sleep over night but take a four hour nap is it like I got a full nights sleep? | There are different types of sleep cycles. What you are describing is similar to a biphasal sleep cycle where you break your sleep up into multiple parts. Throughout college I lived on a sleep cycle of four hours at night and 2 in the afternoon. By breaking up your sleep you don't need as much overall. |
Why do some programs require you use their way of uninstalling them? | > Why do they require I use the program to uninstall it instead of just hitting uninstall in the control panel. Hitting uninstall in the control panel just tells the program to uninstall itself. It's just that most programs will uninstall silently instead of prompting you for more info. But that's not a requirement. |
Why do file sharing sites allow ads with misleading "DOWNLOAD" buttons? | They get paid if you click a fake download ad. They don't get paid if you click the real download link. |
Why are so many products recognized by the state of California to cause cancer/birth defects? | They don't, and the products aren't. California made the rules so broad they apply to virtually everything, and they made the punishment so severe that it made sense just to put it on everything regardless of whether it's carcinogenic or not..Basically they have a list of things that in some cases can cause cancer, ite... |
How can a Company purchase the rights to a drug that has been around for over 60 years? | They just bought the name and it's such a niche drug that no one else makes it. Other folks could make it though, if they wanted to. It's just not a very large market. The company apparently has a history of buying marketing rights to drugs for rare diseases. Ostensibly because they want to do more research into rare d... |
Why does Google Chrome take up so much RAM? | Because each tab in Chrome is like a separate app. That makes it way less likely to crash but it means each tab needs its own RAM and doesn't share. |
Why is Switzerland not in the EU? | They don't want to be. Its not required. Joining the EU isn't a matter of raising your hand and paying a membership fee either. A lot more to it, which includes your laws having to conform to their standards. It has its advantages, but you do hand over some stuff to the EU's control as well.The Swiss pride themselves o... |
Can someone explain the difference between squatting and home invasion and help me understand why a hypothetical homeowner can't just forcibly remove a trespasser. | I suppose it's also worth noting that 'Castle Doctrine', the law that, in extremely basic terms, allows you to kill a home invader, also varies widely by location , but almost always requires you to have a reasonable reason to believe that you're in danger because of the intruder. If you walk into your house and someon... |
Why do the A.P. and Reuters always get news stories first? | I would not say they always do, but they tend to. This is because they have created a business out of literally selling news to other publications and organizations. As a result, said publications rely on the AP to get sources for them. For anyone but the largest media channels, it's cheaper and easier to simply pick u... |
Why does the US government keep publicly stating that they will be air-striking IS? Doesn't this give IS a heads up and chance for counter plans? | What counterplans? The USAF is pretty much unassailable to most real countries. There's very little ISIS can do other than hide if jets show up on the horizon. Besides, the government *wants* ISIS to know they're coming. Publicly declaring that we're going to ruin their whole fucking day, and there's nothing they can d... |
Why does the antibiotic I'm taking, liquefy my feces? | Because it's wiping out your good gut flora while other bad flora that may be immune to the antibiotic are being allowed to thrive. This irritates your colon, inflames it, stops it from absorbing water from the stool. Eat some yoghurt or take some probiotics to balance things back out while taking the antibiotics. |
Why was the United States the only country unable to end slavery without a civil war? | It's really important to remember that the USA's Civil War wasn't just about slavery. It involved other factors as well like a North-South economic and cultural divide. Slavery was more of a very big straw that broke the camel's back. Without the surrounding issues, I don't believe that the US would have split just ove... |

What causes random fleeting aches or pains in the human body? | I'm not sure what it's called, but one can get sharp, yet harmless, pain in parts of the lungs or chest walls. It's scary, though. Pain in the lungs COULD very well be serious, but this one isn't. I sometimes get it around the heart area, which scared the fuck out of me in the beginning. It's happened once or twice eve... |
why do humans have such long life cycles compared to most animals. | Think about other animals/humans in the wild as a whole.Sick? Dead.Broken bone? Probably deadCan't hunt?

Why is nepotism viewed negatively but getting a job through "connections" encouraged? | Connections tend to be judged objectively - you're less likely to view a fuckup favorably. By comparison, few people see their family in a poor light. That cousin that kicked your computer and made it work again? Suddenly he's the director of the IT department, when he doesn't know the first thing about servers. |
Why is the store Decathlon dramatically cheaper than other sports stores? | I don't know of any sports stores, but this is how Harbor Freight is so cheap on tools. They don't own the manufacturers, but the manufacturers make tools exclusively for Harbor Freight. Some of them are in China, some in the US. |
How do people who never eat fruits and vegetables survive? | It's not like fast food is completely devoid of nutritional content. If you go to McDonald's and get a quarter pounder with cheese, a large fries, and squeeze on a few ketchup packets, you'll have about a third of your USRDA of vitamin C. You'll get more vitamin C in your additional meals throughout the day, and in any... |
Why straws hold their contents when you put a finger over them | When you seal it you create a vacuum that holds the water up. The water can't be replaced with air, so the pressure decreases, but water still holds up in the column. Fill a sink with water and put a bottle or glass in it, fill them with water, then raise them out of the water, with the opening under the surface. It'll... |
Why isn't the USPS website a .gov site? | This goes back to the early days of the internet, when the COM domain was serious business. The last part of a website's name -- COM, NET, ORG, EDU, among thousands of others -- is called a _top-level domain_, or TLD. The COM TLD was originally set up for COMmercial entities, such as businesses. Nowadays it's a catchal... |
What is Linux and its pros and cons? | Pros: Free, very good free server software available, more 'tweakable' if you're really into it - which lets you get slightly better performance for certain use cases. Cons: Harder to use, harder to setup, most off the shelf software won't work, some hardware won't work, most desktop applications for Linux are less mat... |
Friction and energy can cause heat, but what exactly causes something to cool down? | I'm going to assume you'd like to know how refrigeration and air conditioning works. The most common mechanism used for these things is air compression. By increasing the pressure of air, basically squeezing it together, we can cause it to heat up, which isn't much use, but here's the brilliant part: when you let the p... |
What makes animals so cute? | The reason for said trait is that we are protective towards anything with some characteristics such as -and especially- big eyes, babies have massive eyeballs relative to their size. that's why we perceive Anime characters as cute for example. |
Why do so many people buy name brand medications for twice the price when most store brands (by law) have 100% of the same active ingredients? | Depending on the product generic while having the same active ingredient isn't always the same The difference can be something as small as not having the same coating to something like the time release not working as well In my experience it varies from product to product Sometimes generic is the same but not always . ... |
does shaving your legs for cycling have a noticeable difference for an average cyclists, or will have it only have a noticeable impact for professionals? | For aero reasons or crashing? Aero perhaps not, but it's apparently easier to scrape the grit out of road rash. |

What exactly is social security? And why does it matter that it wont be there when I'm retired | You pay a portion of every paycheck into social security, and when you turn 67 , you can start collecting a small pension from that fund. It's not much but can be really helpful if you're unable to work anymore and don't have much saved for your retirement. It matters that it won't be there when you retire because you ... |
The guitar and piano seem like the two most widely-used instruments. Is that because of their resonance? Or range? You tell me. | They both allow you to play chords, not just one note at a time, so you don't need another player to harmonize with. Guitars are cheaper and portable, whereas pianos are easier to compose on, are more clearly laid out, and are easier on the fingers. Accordions and 'squeeze-boxes' also used to be very popular, being che... |
Why do I sweat so much? And also why is it that when I'm not sweating and I think about sweating, I start sweating? | I used to have this problem for years. I would go to a meeting and start sweating, especially when I worry about sweating. I went to a doctor and found out it was because I was always dehydrated. I started drinking lots of water . It actually worked. Just drink tons of water. You're sweating because your body is trying... |
Why do fans operate in the order: off > high > medium > low instead of off > low > medium > high? | You go from Off to High to insure that the motor will start. If it doesn't, it can overheat and fail. Once the fan is turning, the lower speed settings can run without danger of overheat. |
If the probability of landing on any one space on a monopoly board is equal, why do people land on Boardwalk much much less frequently? | They're not equal at all. GO and JAIL are the two most landed on spaces because of certain cards and yadda yadda yadda. |
why do negative prescription glasses require a prescription from a docter and cost hundreds of dollars where positive lens glasses can be bought for $3 with no prescription. | Cheap reading glasses only need to bring your focus closer. It doesn't really matter how much closer because they're only supposed to be for reading , and generally mess up your distance viewing. Negative prescription glasses for short sight are specially adjusted exactly for your eyes so that when your eyes are at res... |
why do super morbidly obese (400+lbs) people not have super strong muscles? | Because it's mainly more work on their bones and joints Not muscles in the same way as exercise. |
How does steel affect a MRI, or magnetic resonance imaging, while using it? | The MRI machine is comprised of a large magnet, and just like any magnet will attract metallic objects. Which is why no metallic objects are allowed in the vicinity of the MRI machine. The strength of magnets is measured in Tesla and most MRI machines in the field are of 1.5T . To put that into perspective, the earth’s... |
Why do camera angles change so fast in action films? | It's a combination of several things, most already mentioned: 1) Using lots of cuts let's the actor do more of the action, rather than relying on stunt men. Now that you've noticed this, you'll really appreciate it when you see a long action sequence with no cuts. 2) It's also just become popular in film, over the last... |
What happens when you add extra blood into the body(same blood type) even if you don't need any? | I think of it in two broad categories: the effect of the fluid influx and the effect of the blood components themselves. The person receiving the blood is also at risk of developing one of the many side effects of transfusion. In smaller doses, blood transfusion in a healthy person can have beneficial effects. The incr... |
Which is better: Eating before exercising or exercising before eating? | from my own experience, getting a light a snack, if not a full meal is still better than not eating anyting. At one point I ate lunch at around 14:00, then I was gonna go to the gym at 18:30, at 18:00 I still didn't feel hungry, but when I got to the gym and i was working out, I had no energy, I felt dizzy after every ... |
What were the two plot holes J.K Rowling had written into the Harry Potter series that made GOF longer? | It won't be possible to work out the second plot hole because the only publicly available information about it is JKR saying that it existed in her early drafts. So until and unless she decides to give more info, it's just going to remain a secret. |
We're often told that access to drinking water is a big problem in the third world. Why did people originally settle in places with no nearby water sources? | It's not just the nearness of a source that's the problem, it's the *quality* of the source. When civilization was just starting to be a thing, and your life expectancy was 30, the risk of giardia from your drinking water wasn't that big of a deal, considering how many other things were likely to kill you before that m... |
Why was Hitler's brand of politics called National Socialism? | The far right specializes in pilfering symbols from the far left . So the Nazis noted the popularity of socialism and adopted the term for themselves. However, their version of socialism was different from the standard definition: socialism urges class struggle with the ultimate goal of removing all classes whereas Nat... |
When a squirrel buries an acorn, why does it not start growing? | When they bury them in late autumn it's too cold for them to grow. Most of them will be dug up and eaten before the weather warms up again but the ones that remain actually can grow. Squirrels help the trees spread their seeds.Many oaks and such trees may need a cooling or freezing period before germination can begin |
Why do so many humans have an innate fear of the dark? | Someone posted something before on here, but it's not being alone in the dark that is scary to people, it's the fear of not being alone in the dark.Because we are hard wired to imagine dangerous things when we have no information to go after. This was a good trait evolutionary speaking, those who werent afraid of dange... |
When you join the Navy, Army, or any other armed forces in the US, how long do they have control over what work you do and where you go? | I can attest that the US Air Force offers both 4-year and 6-year initial enlistments. If you start with a 6-year contract, you become an E-3 quicker. The initial enlistment can have you slotted for a very particular job that you'd like to do, or can be one of four different general fields. After your initial enlistment... |
Why didn't Native Americans wipe out the Europeans with their diseases the same way European diseases wiped them out? | [Excellent video that explains this in detail] The core of it is that there weren't any plagues . North America lacked the large centralization of people and animals necessary to generate the kind of horrible plagues that wracked the Old World.I think there are a couple things at play here. First of all, Europeans had ... |
- What is happening with the Spanish economy? | I'm in Spain right now doing a job in news/politics/etc. Spain is *not* that bad off. Greece, Ireland and Portugal were the really wasteful spenders but Spain is still thriving. The problem is, it's getting lumped in with the other countries and so investors are staying away from it, which is slowing recovery. |
If crack is derived from cocaine, why is it considered a cheaper drug? | 1. Baking soda, water, heat source, cocaine. That's really it, explaining any further would be tantamount to a recipe, it's shockingly simple. 2. The chemically pure form of a substance. Formed by seperating the hcl from it, it's then rebound to the baking soda, also increasing weight. 3. It's not really the change in ... |
Why did Japan start a war with America if it was pretty clear they were going to lose? | It wasn't clear - you'd need to predict years into the future to know it would be a losing war. |
Why every british tv or radio show I've ever heard of is on the BBC. | In the UK you pay a tv licence. This is because when TV started the BBC was the only channel and you helped fund it basically. BBC is one of the main channels along with ITV and Channel 4. Because it's funded by us it dosen't have commercials and there are several BBC channels, such as BBC, BBC 2, BBC 3, Cebbiebies CBB... |
Why did Bush and Cheney not testify under oath to the 9/11 commission? | National security, as the Wikipedia article you linked said. If they did have classified intelligence and it needed to be discussed with the commission, that can't become a matter of public record, or even disseminated too widely within the government because of the potential for leaks. I'm removing this because it is ... |
Why is it so expensive to replace a car's transmission? | It's mostly labor because they have to take the engine out to get to the transmission.

Source: know a guy who was on the show and won stuff.Aaron Paul's appearance showcased what a great actor ... |
Why are people worried about asteroid impacts when the Earth has been sweeping an orbital corridor around the Sun for billions of years? | Because Bruce Willis and Ben Affleck aren't really clueless oil rig operators chosen to man a space shuttle and drill a hole in an asteroid so they could insert and detonate a bomb thus destroying the impending asteroid saving us all from a certain death. |
why do some companies pay for paid searches in search engines for keywords their companies' website is ranking #1 in organic searches anyways? | Hi there. Online marketing guy here. There can be many reasons, but the most simple is: More exposure. If your brand name is stated two places the probability for a click is much bigger. Another reason can be that you want the make sure the costumer will end on a high converting landing page rather than your Homepage. ... |
How do creams that you put on your skin help muscles? | You may not want to hear this, but they don't actually help muscles at all. They can provide relief by way of being a counter irritant.

Why don't electric utility companies put their power lines underground so storms don't knock out power? | . It's very expensive to do on a large scale, especially when the poles are functioning well enough already. Also buried lines aren't invincible, and when **they** have problems it's a lot more expensive to dig it up. |
On a scientific level, is art important to a species' survival? | Art doesn't have any importance to our progression as a species. Imagination and creativity are important to our progression as a species, and art is a side effect of that. You might want to point out to your girlfriend that *everyone* works within a bubble. |
why does ordering something from a tv commercial takes so long to be received versus getting it from an online site ? | Because often times a large part of their profit is from overcharging you for the crappy shipping they use which in reality costs about 1/5th of what you paid. Additionally home shopping network, and others like it, are typically geared towards an older target demographic, those that aren't, for the most part, computer... |
How does tread on shoes provide more traction? | They don't provide more friction. They avoid losing friction. Treads allow fluids to flow into their crevices instead of being stuck between your shoe and the floor, in which case your shoe would lose friction because it's touching a layer of fluid instead of the floor. Your train of thought regarding surface area is c... |
If hot air rises, why are the hottest places on earth at the lowest points? | As your altitude increases, the air pressure decreases, causing temperatures to be lower. You won't really see a difference within a house or something, which is why a lot of times in the summer the upstairs bedrooms are hotter than the basement if you turn off the air conditioning. But imagine the air being pressed do... |
Do DJ's actually do anything on stage when performing live? If yes then what? | If you want to know what's happening [here] on top of that pyramid thing-y, then [here's] a brightly lit direct shot of what happens. Basically they're playing live. Though to be fair, Daft Punk could be 17 actors swapping out as their suits heat up, while [Guy-Manuel] and [Thomas] themselves sit in Marsielle. edit: An... |
What happens if I were to connect a NAND gate to one of it's inputs, then power the other input? Would it make some sort of clock cycle? | Since one of your transistors is locked high, it's effectively just a glorified resistor. So your circuit simplifies into a common source amplifier and - depending on the characteristics of your electronics - you're just going to get the DC bias voltage out .You could make an oscillator with two inverter circuits, like... |
Why were alligators euthanized after 2-year old boy got killed ? | They also needed a body to figure out if the boy was actually grabbed by the gator and there wasn't something more sinister happening. |
What happens after Chinese students go to college in the US, then return to China with knowledge of events like Tiananmen Square? | After just spending a month in China, I can ELI5 this really quickly: It's like Americans knowing that CEO's are making 1,000x more than the average person. They know it happened, and it sucks, but that's pretty much it. They seem to focus more on the revolution in the mid-80s more than Tiananmen square. Right now they... |
Why NASA is building a new rocket instead of re-using the Saturn V design. | At this point we'd have to almost reverse engineer the Saturn V, then make it again. It's easier to start over with modern materials & processes than it is to figure out how to use modern technologies to do it the old way. |
Why do people feel mentally clear when fasting? | I have lost about 35 pounds over the last 3 months using a combination of intermittent fasting and fasting. It has been the most effective way to lose weight I have tried. Problem is, while fasting, I am NOT clear headed. I am a miserable fuck. Wife and kids can't stand during that time. It is effective though. |
Why is it that we can hear people talking outside when we're inside a building, but not vice versa? | The noise levels outside are going to be higher than inside if you are able to hear what people are saying outdoors, therefore. Ahh who am I kidding I dunno wtf I'm talking about |
Why the NFL doesn't create brand new teams for LA and Las Vegas instead of moving existing franchises? | Also, I'd say 32 teams is a good number. 2 Divisions comprised of 4 sets of 4 teams makes a pretty standard layout. I wouldn't be surprised if we saw the NHL and MLB bump themselves up from 30 to 32 before the NFL adds any more. |
Why people are against stem cell research | People don't like the process of how the stem cells are generally obtained, as they come from fetuses . |
what is the unspoken bond between smokers where you can ask a stranger for a cigarette and 95% of the time they'll give you one? | Ex-smoker here. You know that really awful feeling you get in your stomach when you're super hungry? Imagine that feeling in your lungs. Now pair it with irritability, headaches, coughing, lack of concentration, and a feeling of utter unfulfillment. That's what it feels like to need a cigarette. I will happily hand ove... |
How is it that the sun's gravity is strong enough to hold planets like Jupiter in orbit but doesn't suck in smaller planets like Mercury and Venus? | You're absolutely right that the speed has something to do with it. So does the distance between the sun and the planet. In fact, that's all that matters. As amarkov pointed out, the force of gravity is proportional to mass. What that really means is that all objects at the same distance from the source of gravity will... |
Why can't countries with lots of zeros on their currencies just knock off some zeros to make their cash easier to handle? | Some of them have. Around ten years ago, Romania took four zeros off their currency, the Leu. 10,000 old Lei were now worth 1 new Leu . But as others have said, it's expensive because you need to basically replace every bill and coin in circulation, as well as educate everyone on what's happening. |
How are homes in poor areas of NYC still 400-500k, like in Jamaica, Brownsville certain parts of the Bronx. How do these low income residents afford their homes/rent? | A lot of families who bought in so-so areas basically became land-rich, cash-poor as the city real estate market exploded. Some family friends bought a big house in a so-so neighborhood in the 1980s for very little. Now it's worth well over a million, but they can't afford to sell it and then pay rent elsewhere for sev... |
Why are Greenhouse gases (like water vapor, carbon dioxide, and methane) able to absorb solar radiation and re-radiate it back? and why don't other gases have this same property? | Greenhouse gases don't absorb solar radiation in the visible spectrum. They absorb the infrared radiation coming from the Earth, and re-emit some of it back. That's what makes them greenhouse gases. |
When you push something at a constant forse it will accelerate, but if i push something at a constant velocity, what will the N-force-value look like? | F = ma The sum of the forces acting on an object are equal to the mass times the acceleration. If something is at a constant velocity, the acceleration = 0. So, your force value is equal to zero. As Arianity stated, if you are overcoming other forces acting against the direction of the velocity , your F would be equal ... |
If human cloning is illegal, how can we be sure countries aren't doing this, and how is this enforced? | Human cloning is rather sensationalised. You can't produce a copy of yourself at the same current age, height, appearance, etc; it doesn't work that way.With the right skills and a lab you can try and make a baby which is genetically identical to you, which is technically a clone, but in the long run it will be essenti... |
How does pawning work, Can I pawn something with no intent on ever getting it out of pawn? | A pawn is a short term, high interest loan. It's intended for those who've kind of hit rock bottom or may not have the ability to get a loan through normal means. The item you are pawning is the collateral for this loan, and it becomes their property if you default. While you can certainly pawn something with no intent... |
Would replacing cables with fiber optic (large scale) increase data transfer rates in application? Isn't the transfer speed limited by the "lowest common denominator?" | Higher bandwidth connections provide exactly that - a higher data transfer capability over that portion of the overall communication route. So you are sort of correct. Your question is very vague and hard to answer specifically but generally to improve throughput you have to measure to determine which aspects of the ap... |
What happens to the money in a cash register at the end of the day? | In addition to other people mentioning that the money is put into the safe at the end of the day, money is also put into the safe throughout the day when the register reaches a certain total. So if the store does $2000 in sales in a day, there won't be $2000 in the drawer at the end of the night, a large part of it wil... |
Why does semen lose its white color after 5 min? | It shoots out runny so it'll come out easily, but it has stuff in it that turns the semen hard almost straight away so it'll stick in the vagina. The stuff that turns it hard it changes the shape of proteins in your semen which makes the colour change . When the effect of that stuff wears off it turns runny again so th... |
Why do fast food restaurants charge less for a combo (entree, side, drink) than they do for just an entree and a drink? | Same reason they have two for one deals. One hashbrown patty at McDonald's costs $0.75 while two costs $1. One patty costs less than $0.50 to produce so either way they turn a profit. |
If I were sleepwalking does that mean I gave my consent to my s/o to initiate sexual actions..? | Are you talking about whether the other person would be liable for rape or not? I'll answer assuming you are. Where I live , to be liable for rape the defendant must know the victim does not consent, or be reckless as to whether they consent or not. In that situation it definitely wouldn't be a case of the defendant kn... |
What is it like to smell? | Taste is akin to touch; it happens in a very specific location, and only in direct contact. You 'feel taste' with the specific part of your tongue that the thing is touching. But smell is more like hearing; you don't really 'feel sound' with your ears, it's just something happening outside you. In the same way you don'... |
What is the numbing sensation that washes over ones body when confronted with a negative and emotional situation? | This actually ties in with another question poster a couple of hours later in ELI5, 'What causes our spine to ''shiver'' ?'' The only answer so far posted does give a very satisfactory explanation regarding harder thumping, tingling fingers and numbness. I'm pasting it bellow. [–]ICUGOD 2 points 7 hours ago there are m... |
Where does candle wax go? | When you burn a candle, the flame melts the wax, then the wax gets absorbed by the wick. It's the liquid wax that actually burns, not the wick itself. It reacts chemically, and turns into some combination of soot and gases, like carbon dioxide. That gas does not solidify.Do you know the general formula for combustion? ... |
How do bees pollinate? | Bees don't care about the pollen. They're after the nectar. Pollen on the stamens just gets in their way and they brush it aside and sometimes get some on them. |
Why do dead batteries bounce better than full ones? | according to [this princeton page] it's because drawing charge from a battery creates microscopic zinc oxide connections inside the battery that transfer kinetic energy better. they use it as a golf ball filling so it's fairly legit. it also says that it isn't an effective way to tell if a battery is dead, though, only... |
How did old civilizations deal with fish and nut allergies? | Allergies were less common, it is hypothesized that's because they lived in way less hygienic environment with dirt, shit and parasitic worms everywhere.

Why is it so difficult to mix raw cocoa powder and cold liquid? | Wouldn't the natural cocoa oils and fine particle size also contribute to the cocoa holding together better? Something about polar and non-polar molecules |
How did nations know where to draw the line for their borders? | Nations agree to where those lines are. If they do not agree, it often leads to international conflict or outright warfare, and that's really bad for business and government and people and stuff so leaders of countries generally prefer to work with their neighbours. So once they're set they usually stay the same for lo... |
How do the O2 monitors you clip to your finger work? | So those finger clips don't actually measure oxygen saturation. They measure how much infrared light is absorbed by the cells. So let's say you were in a burning building and happen to inhale quite a bit of smoke. The O2 probe would probably read 100% because most of these finger probes cannot tell the difference betwe... |
How are commercials cost-effective to a company? Has anyone ever seen a comercial and thought, "Wow! I'm going to go buy that." | ROMI or return on Marketing Investments are generally very difficult to objectively quantify. Many companies justify the costs of large marketing campaigns not because of the immediate return but rather the purchases made by brand or product awareness. In these cases, most customers are casually shopping and will purch... |
What is the big deal with all of the corn based food products? | Corn is a simple carbohydrate a starch. It is easily converted into glucose and causes insulin spikes and contributes to weight gain since the human body isn't really designed to run on simple sugars. |
