why do veins in arms or hands kinda have random positions?? | [
"They don't! There are actually loads of named vessels at certain landmarks.

Why when you get up from your chair really quickly you lose your balance and your vision goes black? | [
"Because you experience postural hypotension - low blood pressure with a change of posture (usually from lying or sitting to standing). Not usually dangerous and often just a symptom of having generally low blood pressure."

"Pro tip: If you ever stand up too fast that causes you to get lightheaded and sometimes makes your vision fucky or something, flexing your abdomen will actually make it stop. Not sure why, just learned it and it works for me."

Why should you test GFCI outlets and breakers once a month? How can they fail in an unsafe way? Is there a reason they don't fail safe? | [
"If you electrocute yourself, the GFCI is supposed to turn the power off. If it's failed, then it won't turn the power off and you may die. They cannot really be designed to fail safe, because you want them to move the switch to the off position when they detect you electrocuting yourself, and there's always the po... | [
"If you get a brief zap when touching the button, it is static which is harmless. Static electricity can be made by walking to the elevator.

Why are sounds louder on one side of your ear when you cover the other ear? | [
"They're not actually louder - there's not suddenly an increase in the ambient sound coming into the ear canal - however, with one ear covered, your conscious awareness of what you're hearing increases."

"Sometimes, one of my ears will go deaf for a few minutes and all I can hear is ringing (think being too close to a grenade in Half-Life 2 when it goes off).

How does television put 10 pounds on someone? | [
"It's an expression, and isn't literal. Movie and TV cameras have a slightly rounded lens to capture a wide angle, which can kind of stretch out the image of people. This gives the appearance of being a little wider than normal, making it seem like you are a few pounds heavier."

How come when our body temperature is above normal, we feel colder? | [
"it's less that your body temperature being warmer is making you feel cold and more that your temperature sense is off. when you have a fever, you get chills because your body is actually trying to raise its own temperature since the fever is an immune response to fight infection."
] | [
"Because the skin is on the outside of the body. So they sense the cold from the surface of the skin just as anybody would. Whilst it would make a difference for the internal organs, most people's feelings of cold and warm are only skin deep (so to speak).

why can your weight change so quickly (like gaining weight after going off of a diet or losing weight after not eating for a few days) but it takes so long to get back to your original weight? | [
"Short term weight changes are either due to water or colon content. It you eat like a regular person, you have about 500g og glycol stored in your body as short term carbohydrate store. These sugar molecules bind about 2kg of water. If you ran on a diet, your body will first metabolize those stores, so you'll lose... | [
"Many times weight fluctuation is caused by water weight. For example, it you drink too much water the day before your body flushes out and will weigh more.

"Hard surfaces reflect sound very well. Swimming pools tend to be tiled and concreted. So the sound bounces around everywhere making for a mass of echoes and reverberations."

If all of our cells are replaced every 7-10 years, how do tattoos last a lifetime? | [
"The tattoo ink sits between layers of cells rather than staining the cells themselves. Little bits are cleaned up by the immune system over time, but mostly the ink just sits in a layer than the body doesn't pay too much attention to."

How and why does supernova's happen? | [

"In a nutshell: as a star ages and consumes it's fuel it begins burning heavier elements.
