How come you can use a password, or a combination to a lock, every single day or even multiple times a day and then one day out of the blue you just forget it? | [
"You've probably transitioned to muscle memory.

What is happening to our bodies when we are having a food coma (feeling really tired/sleepy after eating large amount of food)? | [
"After eating a large amount of food, your body engorges your digestive system in blood in order to transfer the raw materials (vitamins, nutrients, fats, proteins, carbs etc) away from your digestive system and where they need to go in the body. During this process your blood sugar rises, which triggers your body ... | [

Why is the price of gasoline in the US advertised at 9/10 of a gallon and not the full amount? | [
"It's not. The price adds another $0.009 (9/10 of one cent). That's just another throwaway tax, that Americans don't even notice."
] | [
"The two main reasons are: 1) A UK (imperial) gallon holds roughly 20% more volume as compared to a US (customary) gallon. So, the US price you should compare it to is $4.20. 2) The UK (as with most European countries) has much higher taxes applied to gas (aka 'petrol') sales.

Why airplane manufacturing companies don't put some kind of a net on a jet's turbines? | [

Why are most flags shaped like a rectangles? | [

How does the body know where to make collateral bloodflow when an artery/vein has been damaged or blocked. | [

However living tissue that does not receive enough oxygen sends out signaling compounds into the surrounding connective tissue that encoura... | [
"Not every blood vessel is necessary. You have an entire network to shunt blood around, blocking off 1 or 2 vessels just redirects blood somewhere else. It’s like traffic redirecting traffic.

If water freezes at 0˚C, why does my car warn me of ice at 4˚? | [
"Because there still could be ice on the ground. It could be melting but not completely melted yet. They warn you early to give you advances notice of conditions that could potentially create ice."
] | [
"No, water does get somewhat denser if it is frozen at colder temperatures. Additionally many plants have chemicals and enzymes in them that lowers the freezing point of the water in their cells. So the water in them might not freeze until the temperature is 10, 0, or as you state -20."

Why is local produce more expensive than non-local? | [
