What do goose bumps do?!
Question: I know that when you're cold or scared, you get goose bumps and your hair sticks up... but what do they exactly do? do they absorb heat? do they have something to do with personality? why do they arise all over your body? or do they arise at certain places or body parts?
Just curious!

Its a part of the bodies nervous response mechanism. When this fight or flight response is activated your body raises up the hairs in its skin to trap a small layer of air to keep you warm. Each follicle of hair has a muscle in it to help the hair stand up for this purpose. Ever notice you get goose bumps when you're cold? This is why!
They don't have a purpose. It's just one of those weird things that the human body does. Some people do get them more often than others.
The muscles (arrector pili) contract to keep heat from escaping from your body. I'm not sure why it happens when you're scarred. But maybe it just happens on the parts of your body that sense the temperature change. I hope that helped. Good luck!
Goosebumps are the erector pilli muscles of your hair follicles contracting to make your hair stick up, which helps you keep warm to an extent
not much now in the modern person, but back in the day, when humans walked the same planet of a lot of beasties that would eat us as well as look at us, it was like a radar that let us know that we should flight (run) or (fight). most took the flight method. it means you have to react to the situation at hand.
the muscles contract and the hair traps heat
i dont know why you get them when you're scared to death though
