Ever wondered how many times a minute you blink? Or how big your brain would be if you removed all those wrinkles? Or how long of a line you'd get if you stretched all of your veins in one line? Our bodies are such fine mechanisms, that it's always really interesting to find out what makes those systems work so well. 

For example, did you know that not all of us experience goosebumps? Some scientists have suggested that goosebumps are an evolutionary holdover from our early ancestors who kept themselves warm through the heat they managed to retain beneath their hairs of skin. Your body is many things in one: it's a walking chemistry set, a sustainable life form, a complex biological phenomenon. So there'll always be something to learn about the body, always something to find out about its marvels.
