10 Crazy Things Your Body Can Do

The Mind Can Remember Almost Everything

While the idea of people having photographic memory is not something that most scientists believe in, there is documented evidence for people being able to recall details of any event from all sorts of dates in great detail. This effect can even be taught to those with poor memory, using techniques such as mnemonics and encoding, so that they can remember almost anything they want at will.

While the body has plenty of ways to tell when it is cold, though these usually just involve things like shivering when the temperature drops to a reasonably chilly temperature. There is in fact one sure way that the body can tell you if it is becoming dangerously cold, through the eyes. Once temperatures get to this level, blood vessels in the eyeballs begin to constrict to save energy, causing temporary blindness.
