Why are there worries about micro-organisms from Earth affecting potential micro-organisms from other celestial bodies and vice versa, when they haven't adapted to do so? | Lets say your eating Cheetos. Your hands and face get covered with Cheetos dust. While covered in Cheetos dust you get sent to mars to see if its surface contains Cheetos dust. Well if your covered in it, your tests will show there's Cheetos dust. The point is really to protect the reliability of scientific experiments... |
Pros and Cons of private/for-profit prisons. | This is obviously a controversial issue and I'll try to keep these as unbiased as possible. Pros: * Fixed costs for governments.

Why do people double-check $20 bills, than any other bills? Are there so many fraudulent $20 bills than any other bills? | $20 bills are actually one of the most counterfeited bills now-days. They used to do larger denominations, but running around with a bunch of crisp new $100 and $50 bills was a bit too suspicious. They could have used smaller bills, but counterfeiting is expensive and risky, so you want to have a little more bang for y... |
What is a Cartel? How does it work? | A cartel is an arrangement between companies or organizations that would otherwise compete with each other so that they can manipulate the market.

Why did everyone protest the changes made by Ellen with boycotts and petitions, but aren't doing jack squat about the continued changes that are being implemented by the new CEO? | Seems to me that she made changes and we thought that she was dictating them on the community. When she left and the changes remained and the doctrine remained, I think there was a fatigue that she was not the problem and the fight remained. People are living in the moment of victory and not seeing the lose all around ... |

If someone tr... |
Why are more men in the US overweight, but twice as many women who are classified as extremely obese? | Let's put aside the whole "what defines obesity" etc thing for a sec. Just believe that there is a definition that those numbers are derived from. Then, it just means that while fewer women are fat, the fat ones tend to be REALLY fat. Conversely, men are fatter generally, but they don't tend to be blimps. I know that t... |
Why can't they make DSLR's with a "superzoom" capability? | It's a matter of the size of the image sensor the tiny little sensor on a super zoom camera has a 'normal' focal length is, what, 11mm? So the 600mm equivalent on a 35mm camera is actually is maybe 125mm in reality on that tiny sensor. A DSLR has a much larger sensor, close to the size of a 35mm film frame, so you're g... |
How do front-page posts only have roughly four to five, sometimes six thousand upvotes when millions of people visit reddit each day? | Not when you consider how selective some people are about the subreddits they frequent. For example, the current top post on my front page is [this TIL], which has 4,878 upvotes. While there are nearly 8 million subscribers to TIL, only 12,812 are on right now. The post is also only 4 hours old - that means Redditors o... |
How are documentaries allowed to follow people around that do illegal activities and not have to report them? | There are no laws that require the average person to report crimes. The big exception is teachers, medical professionals, etc have to report any suspected child abuse', "There this thing in France called non assistance to a person in need. I assume that a variation of that law is in other countries' constitution. There... |
What is the purpose of having a Concert hall volume option? | The purpose of the setting is to digitally simulate the slightly delayed echo effect of a large venue. While in a small room both the soundwaves coming directly at you and the ones bouncing off your walls, floor, etc, hit you at essentially the same time from a human perception standpoint; you are technically hearing a... |
Why do matches appear to produce a lot of smoke the moment they go out? | When wood is heated, it produces a bunch of gasses and carbon particles that will catch fire if they're hot enough. If the gasses aren't hot enough, they'll show up as smoke instead. So what you're seeing is basically what fire looks like when it's not burning. |
When downloading a song and its is stopped halfway, why can you not listen to the audio until it's fully downloaded? | The downloading happens in parts, not chronologically. For example, first the 400th of the 1000 parts is downloaded, after that the 900th and so onThis depends on how you downloaded the song. If you used Bit Torrent, the data is fragmented - meaning that the data you already downloaded is not necessarily in the right o... |

Does pumping oil out of the ground leave huge empty underground caverns? If so, why don't we wind up with enormous sinkholes? | Oil generally doesn't form a full pocket of oil. Think of it like sand on the beach. If you dig a hole near the beach, the hole will fill up with water that leaches out of the near by sand. Depending on the type of oil being extracted, the oil can be inside porous rock, like [oil sands], which looks and feels like stic... |
why are the numbers on a phone keypads and computers reversed? | Computer keypads mimic adding machine keypads, as they were originally only used for offices. It allows the worker to input hundreds of numbers more quickly, because on average, the lower numbers are used more frequently. The lower numbers are closer to you, so you have to move less to input the sums. For most of us, t... |
Even if we know movies are fake, why do some disturb or scare us? | YOU know it's fake, but your subconscious brain does not. It doesn't understand fiction or context as well as we do. So when you see a horror movie your subconscious brain thinks it's real and your are disturbed by it. |
The extended Euclidean Algorithm for finding Modular inverses | Well, remember what 13^ needs to be. Let's call y the variable we are interested in, that is some integer which is 13^ mod 60. By definition of inverses, we know y * 13 is congruent to 1 mod 60. So, this means when you divide 13y by 60, you get a remainder of 1. This means there is some integer x so that 13y + 60x = 1 ... |
Why are there so many different SIM card sizes when the 'chip' is always the same size? | You can ask the same question about file formats or usb connector types.. For something that is made in big numbers with machines to be used by many people, it must be made in the same way each time. In order so that we don't have to make a special sim card for every phone model we just agree on a size. We call this st... |
How do neurons send electrical information for different processes? | It depends on what the neuron sending the signal is connected to. Some are connected to muscles, others are connected to hormone-producing glands. |
Can you get immunity to 'Bombay Belly'? | You can. Otherwise everyone in Bombay would have it.

How come it's recommended to wash your jeans as little as possible? | The denim do not handle water very well and will start disintegrating if you wash them. However they do not accumulate much dust or dirt either so they do not get as dirty as other types of cloth.

For extra safety, rinse the fruit off. For even more safety wash with soap. Even more, very hot water and soap. One... |
what does a conductor for a orchestra actually do? | It helps a lot to have a visual aid that everyone can look at and sync with. You can know a composition inside and out, but it's hard to keep perfect rhythm, on your own. The conductor provides this visual aid as well, and by his movements and actions the orchestra/band is clued into when to play powerfully, when to pl... |
Why does the internet advertising model support obtrusive pop-ups instead of running the ad on page like traditional printed media? | Almost all the people I know won't bother visiting certain sites that have those awful pop over ads, not the actual seperate windows but the in-browser popups that you can't click behind/off without finding a tiny X button. The worst for it is a website called \'Wired\', they have 2 of those popups, 1 is an ad that pop... |
Why is it that Muslims are often hesitant to condemn other Muslim terrorist organizations? | Just last week there was a protest at 2000 mosques in Germany by Muslims and Muslim groups, condemning IS. Furthermore, plenty of normal Muslims see Islamic extremist groups as being so far away from their brand of Islam, that they feel no connection to them at all. The vast majority of Christians in America feel no re... |
Why are our ears shaped so wierd? | The shape of our ears does two things. Firstly, it exaggerates the narrow band of sounds that make different parts of speech sound different. By allowing us to hear those parts louder, we are better able to understand speech. Secondly, they distort sounds that come from above or behind you. We use that distortion to de... |

Why do portuguese and Spanish people speak so fast ? | May seem fast to you, if you’re trying to understand what they are saying it may sound like a bunch of long gibberish. But if you know the language generally you understand it as a normal conversation in your language. Other people who aren’t fluent in your language think the same way, everyone just wants to understand... |
about laptops, phones and more... | wait what breakthroughs has apple been making? Maybe we are thinking of a different company but their current laptops are a disaster. Their incredible innovation this year was removing the headphone jack, i guess thats innovation. Also thinner phones come from more transistors being on the same size or smaller chips. T... |
how we know there are more then 3 dimensions and why we're limited to 10 | The 10 dimension theory is part of [String Theory], which is ludicrously complicated, not proven, and I can't even begin to ELI5 it. Here's a simplification that [UltraCulture made]. While we don't know for sure if there are higher spatial dimensions , we can at least start to think of what a 4th spacial dimension woul... |
Does a dog recognize an infant (by smell) as a combination of it's two masters? | Babies have a scent all their own. There's something about the smell of a brand-new baby that makes me want to go out and have another. That said, it was amazing how quickly our dog decided it was her job to protect our new baby from 'intruders'. I had an aunt come to visit who very nearly was not allowed up the stairs... |
How does my bladder fill with urine? Is it like a empty balloon that fills up? Does it push other tissue out of the way when it fills up? | Yes. Your bladder is very much like a balloon: it collapses when it is not full, but it also stretched to fill up. During an ultrasound, a full bladder is obvious as a large dark space, which becomes much harder to see if the bladder is empty. Yes, organs move around inside of you, as they are only loosely held in plac... |
How come when I put vodka in my slurpee, the slurpee immediately melts and the outside of the cup has ice forming on it? | Because the slurpee now has alcohol in it, which has a freezing point much lower than water. But since it is still below the freezing point of water, ice forms on the outside of the cup, since the liquid inside is cooling the cup itself. It's the same reason that if you stick a bottle of rum or southern comfort in the ... |
How can internet speeds be 1GB+ when computer's write speed is no where close to that? | 1. You're conflating mega/giga BITS with mega/giga BYTES. 1 GigaBIT is 125 megaBYTES. 7200RPM hard drives can get 70-90MB/s so even without a SSD you'll get pretty close. SSDs can get ridiculously fast, even consumer ones. Example: Intel 750 series drives can get a sequential write speed of up to 1200MB/s, or 9.6Gigabi... |
If you had a light source in the middle of a perfectly mirrored box, what would it look like inside the box? | So you're kind of playing with magic unreal physics here but let's give it a go. Let's assume your magic light is just entirely and completely a source of photons - no heat is generated, nothing can burn out, and it has no base or mount and hovers in the middle of the box, emitting say a light-bulb's worth of photons c... |
If games are made on PC, why are PC ports nightmares compared to console? | Ex-game dev here. Console games are made with specific constraints in mind, such as limited FOV because players are sitting 10\' away on a couch, controller input only because that's the only input option, and no graphics settings because everybody is on the same platform. Depending on the development schedule, PC spec... |
Why does electricity make a humming noise? | The alternating current causes magnetic fields to shift back and forth quickly which causes metal enclosures to vibrate. This vibration produces a humming noiseYou cannot hear electricity. What you are hearing are the effects of electromagnetism on other materials. Powerstations use huge transformers. A transformer is ... |
What was the time frame for the asteroid that caused the dinosaur extinction? If humans had been alive at the time, how much warning would we have had? | The Chicxulub impactor is thought to have been about 10 km in diameter. An asteroid that large we would probably have spotted already, asteroids orbit fairly close to the Sun which means they're always fairly close to us. If one was found anew we would expect decades of warning, although less is possible. 99942 Apophis... |
how do air raid sirens produce such a loud noise just by spinning? | Honestly, I don't recall, but [this video] on YT does some explanation --- as well as describing how to build one. It's pretty easy to fall down the rabbit hole of that guy's videos though.Sound waves are alternating high and low air pressure. For example, a guitar string vibrating back and forth pushes and pulls on th... |
When something enters the sea does it make the seas level rise? | Yes, but since the sea is extremely wide, the effect is too small to measure. If all the ice on Greenland fell into the sea, *that* would raise global sea levels by a few metres.It does, but by a microscopic level. For example, a medium sized ship can displace about 45,000 cubes of water. The Pacific Ocean alone has 7.... |
Why do the birds don't get a shock when the sit on the electric power cables? | Birds most likely feel the electrical field surrounding the cable but to feel the shock you have to complete the circuit. If they were to touch two wires at the same time they would most definitely fry. |

What conditions cause snow, sleet, and freezing rain, respectively? | Snow is caused by temperatures inside the clouds that are slightly below freezing, so the snow flakes can form gradually. Also, the exact structure of the cloud has to be right to ensure the snowflake forms at the correct rate, otherwise it will just fall as hail. Sleet is a mixture of rain and snow, and is caused by t... |
Why are computer monitors so much more expensive than TVs that are the same size? | Computer monitors use a higher resolution than televisions, until you get to a true 4K television display, and of course those televisions cost more than computer monitors. Edit: There are 4K computer monitors, but I don't believe there are any 4K televisions that currently share the same size to give a fair price comp... |
Sleep Paralysis & the shapes and shadows you see during the experience | When asleep, you're paralyzed. However, you can wake up while being asleep. The thing is that your brain does not know that you woke up, so you will hallucinate. The hallucinations occur because the brain still produces the dream images, but combines them with the image of the world, hence you see monsters or creepy fi... |
How are exit/opinion polls calculated during elections? | They pollsters know the voting patterns of each constituency, based on decades of poll results. They can sample key locations, and use that as the basis for an analysis of how that area will vote. |
Is it possible for someone to conduct a background check on themselves? If not, how do employers get this information? | There are plenty of background check services. They'll give a report to pretty much anyone who will pay them. If you want your own background report, just pay one of them for the service, or ask your employer to give you a copy of the background report that they got on you. Most of the time it's rather boring, your pub... |
why do soap operas always have such horrible acting? | Everything about soap operas is terrible: * terrible writing - at 200+ episodes a year, there is just no way to keep up anything resembling quality* terrible preparation - actors typically only get a few hours to remember their lines before filming* terrible directing - episodes are typically filmed straight through wi... |
how does government debt work | Yes, and yes there are whole markets devoted to government bonds. Government debt works the same as any other kind of debt with a couple of important details. Since governments have the ability to print money, and have a infinite lifespan their ability to pay debts off is much much larger than a individual. What this e... |
Why do we make weird faces while working out? | Whenever you move your body consciously, a your brain called the *motor cortex* controls all the motions your body makes. Both our sensory cortex and our motor cortex have certain general areas that represent different parts of our body. Your face is only a fraction of the surface area of your body, and yet it takes up... |
Why do parents use jealousy tactics to make babies eat, how does this work? | I don't think that it's jealousy tactics but merely making the baby feel comfortable to know that the food is safe to eat. Adults do it all the time when testing a foreign food. They hesistate until someone they know takes a bite and didn't throw up before they try it out themself. |
Gay- Lussac's Law (Pressure-temperature law) | Gases are made of these things called molecules. These molecules are smaller than anything you can imagine, but they are also faster than Superman. Now let's say you fill a one liter jar with air and seal it so tight that no air can escape. These molecules are still flying around super fast and some of them will collid... |
What's the deal with goofy-looking bowling shoes? Why can't they just look like regular shoes? | IIRC, it's to prevent theft. They are ugly so no one will want to steal them, and readily identifiable so if someone does steal them, everyone will know they are a thief. And at one point many small towns only had one bowling alley, so if anyone wore those shoes, it was apparent where they had been stolen. |
why is monogamy the norm in most modern western societies? | Polygamy creates highly unstable societies. This is often referred to as the 'surplus male\' problem. Essentially, everyone has an impulse to procreate - even if you don't recognize that impulse as such. Women rarely have an issue with this - they can easily procreate simply by being flexible in terms of how they offer... |

Why do people tend to sleep on one side of the bed instead of in the middle of it ? | Comfort. The edge of the bed tends to remain firmer over time. Most people find that sinking into their bed is uncomfortable, which is what happens when sleeping in the middle of the bed. |
How Facebook got my Amazon search history when all of my trackers are blocked. | Are you accepting cookies from Amazon? It It could be as simple as that. There's plenty of other theoretical methods, such as your Amazon and Facebook accounts being linked by e-mail address, or first-party browser fingerprinting . |
Why do older generations look more mature and older at "x" age than current generations at "x" age | Are you talking about when you look at a picture of your dad when he was 20, and compared to 20 year olds today, he looks more mature? It's probably just because of his style the type of clothes he wore, how he wore his hair, etc. You associate that style with older people because it's the style of older generations. W... |
[culinary custom] Why do people eat dessert after a meal? | Eating sweet is introducing sense of fullness and you lose your appetite. That's why you get it at the end, to finish. Without a dessert I can eat 2 main dishes. After the first one there is still sense of hunger. I could go without the second one and eventually automatically lose appetite after half an hour, but I can... |
Why movies aren't filmed in chronological order. | They don't need to be, everything can be put in the right order when it comes down to editing. If you're going to have a scene at the beginning of the movie and at the end in a house, it makes more sense to film them both at the same time so you don't have to haul in all the equipment for filming two times.think about ... |
How do people figure out how to replicate odd flavors to add to jelly beans or drinks? | When you have a good palate you can start to combine smells and tastes the way a painter would combine colors. There is a low barrier to entry, like you know combining apple and cinnamon will taste like apple pie, so you might make a fireball and cider drink. As you go along you realize the effects that acidity, oil an... |
Why do schools specify "NO DIXON BRAND" pencils in the school supply list? | Are you sure it isn't "No. 2 Dixon Brand"? And "HB" is the same as "No. 2," so it seems odd that a school would specify *not* bringing the most popular weight. Sounds more like the schools are *requiring* Dixon brand or at least No. 2/HB pencils. Could that be?', "I'd never heard this before and thought you were making... |
Why does acne appear mostly on people's faces and not elsewhere? | Acne is also common on the back and upper arms, many people suffer with acne there. But to answer your actual question, it's because the facial skin is more porous than skin in other places leaving it more susceptible to blockage which leads to a minor infection aka: acne.Acne is common on the shoulders, arms, back, an... |
Why are we fine being hot in the winter but not in the summer? | In most cases "hot in winter" in far colder that "hot in summer" With the heater on and the fireplace on, the temperature will be between 25 and 30°C. In summer at 2AM, you're fine if it's only 25°C you have a problem when it's 40°C', "Very often, discomfort with heat is a question of humidity, not temperature. A high ... |
How is a degree from a place like Harvard or Yale any different from a degree in the same subject from somewhere else? | For starters, many of these places have good reputations because they have cutting edge research and the best academics who are at the forefront of their respective fields. It should be noted that this doesn't always translate to the best *teaching*, but that might well be beside the point. Some economic theories of th... |
for any offroaders out there, how exactly do locking differentials work, or lockers for short. | there are basically 3 types of traction aid: Limited slip Locker and spool The limited slip usually uses clutches and transfers power from a spinning tire to a non-spinning tire. There is at least one clutchless limited slip that I'm aware of. These are good for front diffs and rears if street manners are highly import... |
Why does it seem like guerrilla warfare is the only type of warfare nowadays? | A) It's not. None of the western powers practice it for the majority of the time. B) Because that's the only option small militias have. Ever tried mounting a frontal assault on a government-backed fighting force with 30 people? Don't, it's a stupid, stupid idea. Stay hidden, strike only when you have every advantage, ... |
what's a mosquito bite look like from the inside? | Mosquitoes drink blood^ . To do this, they need to circumvent the body's natural response to a breached blood vessel, which is to clot the blood and block the opening. To keep the blood liquid, the mosquito injects saliva containing various proteins into the wound. These proteins, while serving as an anticoagulant, als... |
Why do head/scalp massages feel so intensely good? | IIRC: It triggers a dopamine response that has a calming de-stressing effect. Mothers gently touching an infants head while nursing, then later washing and brushing their child's hair calms them and makes them feel safe. Animals do this with grooming their babies as well. The licking and grooming is key to the young's ... |
What is aftertouch? What would I use it for? Would I miss it if I didn't have it? | The most basic MIDI keyboard just sends note on/off messages. This is enough for basic music but doesn't give you much room for dynamics & expression. \'Toy\' keyboards will do this. The next step up is to send velocity data with that message - this is how hard/fast you hit the key when you first play it. This lets you... |
If Social Media and the Internet is so important to the infrastructure and recruitment of ISIS, what stops telecommunication companies and service providers from stopping all service to ISIS-contorolled areas? | First, shutting down the internet is hard.Iraq throttles a lot of their information and monitors it extensively, but it's so far fairly ineffective at stopping it from getting out. Assad recently [shut down Syria's internet] but this was only for a short time. Egypt, during the recent uprising also "pulled the plug" bu... |
Obama's spending in his first term. | People accuse Obama for a massive increase in spending in 2009, because he took office at the start of that year. However, budgets are approved the year before, so the increase in spending in 2009 is from the Bush administration. If you only count the years for which the Obama administration is actually responsible for... |
Why are card from a deck in just 2 colours and not 4? | Not sure why it initially developed like that, but some card games rely on the two colors just as much as or more than they rely on the individual four suits. Four different colors would just confuse things too much. And solitaire would become a lot more difficult. Lol |
why can you eat a pound easier than you can drink a pound? | Assuming your talking about the weight, not currency, I'd disagree and say chugging a large glass of liquid is easier than chewing on a plate of food", 'It depends on how dense the matter we are drinking or eating is. I can drink a pound of water much easier than eating a pound of kale or marshmallows.Because usually a... |
What is so great about the Dr Dre Beats headphones? | > Why is everyone spending $150+ on these? Because marketing. > Are they really that great? NoI remember hearing a story when I first started working with customer service. two customers are shopping for a frying pan, there is a 20 dollar pan that has all the features you are looking for, and a 30 dollar pan that has a... |
Why doesn't Apple make iPhones that can use only one kind of headphone, thereby essentially forcing everyone to buy headphones made by Apple? | The backlash would cost them sales and bad PR.There were [rumors] before the iPhone 6 came out that they were getting rid of the headphone port to make the phone slimmer. That obviously didn't happen, but you weren't far off with your thought.Rumours after Apple bought Beats suggest that is likely to happen soon. |
Bail. Why is it acceptable that people can pay to leave jail before sentencing. Isn't that an opportunity to run for it? | > Isn't that an opportunity to run for it? That's why they make you pay bail instead of just letting you go. You can run, but that's just another crime they will charge you with when they catch you, and they keep your money. Also, conditions can be put on your release, monitoring devices, surrendering passports, things... |
How does pulse oximetry work? | The sensors are infrared. Oxygen absorbs IR. The amount of IR emitted and received are recorded. The difference tells how much oxygen there is. It is quick because they are using light waves. The difference is directly proportional to the oxygen in the blood. The IR sensors are responsive enough to take multiple measur... |
Can you walk on Mars with just a scuba tank? | No. The key purpose of the space suit is not to provide you oxygen to breathe, but rather to maintain a safe air-pressure level. The pressure on Mars is extremely low, 0.6% of Earth's. This will cause the gasses in your bodies to expand. This is extremely uncomfortable and can quickly lead to death. If one is holding t... |
Is there a reason other than that germany lost the war that the flight and expulsion of germans after WWII is not labelled a crime against humanity? | > Is there a reason other than that germany lost the war that the flight and expulsion of germans after WWII is not labelled a crime against humanity? Not really. Many of the Germans fled from Eastern Europe as the Red Army advanced and the more organized expulsion that took place after the war was more or less explici... |
Why do our faces get red when embarrassed | The simple answer is that the veins in the face get bigger, and that looks red. It's triggered at least partly by the sympathetic nervous system stimulating beta receptors in facial veins. A beta-blocker like propranolol blocks those receptors from being activated, and can reduce blushing. The complicated answer would ... |
How do people develop their sense of who they find attractive? | As most people have already said, it's probably based on a particular affection towards someone of a similar appearance, during one's late childhood/early teenage years.Generally speaking, it's a mix of cultural influences and individual quirks that drown out most commonalities. But under all that statistical "noise" t... |
on a hot day when we're thirsty, why do we crave things like soda over just water? | You've trained yourself wrong. Also, try cold water. Warm or lukewarm water doesn't compare well to cold beverages when you're hot.People say that if you have ever been **truly** thirsty , the only thing you can think about is water. In non-life threatening situations, you just enjoy getting the sugar/carbination/etc o... |
Why flies fly towards to light? | Many insects navigate by the sun. Since the sun is so far away from them it will stay in relatively the same place in the sky for an extended period of time. If they keep the sun in the same place in relation to their body they can then fly in more or less a straight line. When its dark and they cant see the sun, thoug... |
Why does depression in young people seem so common now? | Being diagnosed just means it's enough of a problem that it's medically concerning, not necessarily that they have a life-long mental illness. Plenty of psychiatrists are a bit dubious on given a diagnosis at all to teenagers that aren't showing severe symptoms being as teenagers are really prone to mood swings and epi... |
What is the double slit experiment, what was learned from the experiment, and what does it prove? | It shows that light behaves like a particle and like a wave. I am not sure how I'd explain this easily, beyond maybe saying it shows that there is still a lot of mystery left in the world and this is something we can observe but not fully explain yet."If you can explain this using common sense and logic, do let me know... |
why do so many game controllers use the button names ‘A, B, X, Y’? | For the simplest reason of all; that's how the first 4-button game controller by Nintendo on the SNES was labelled, and other companies, trying to reach gamers used to Nintendo's consoles just adopted the convention on their systems as people were used to it. |
If a plane's engines stop working mid-flight would the plane descend uncontrollably or would the pilot be able to maintain some level of a controlled glide until crash? | That depends a great deal on the plane and the circumstances of the engine power loss. For example, does the plane have electrical power sufficient to operate the flaps? How fast was the plane going and at what angle of attack? Some planes have the ability to glide a good deal, others glide like a hurled brick.This is ... |
