Does the body replace itself?

Does the human body really replace itself every few years? The answer is yes, but different parts of the body do so at different rates. Learn all about which parts of your body are the speediest, and which take the longest to regenerate.

Over the last little while I've picked up on some interesting information that, on their own, aren't really enough for a post each. Put together, though: look out! 1) Most of the wildlife photography I've ever seen was probably faked. Disney was long ago exposed for staging the lemmings running off the cliff scene in the nature film White Wilderness, which forged the lasting idea that lemmings are suicidal. As I learned recently, that tradition continues in the form of game farms. Most of these farms were initially established as wildlife preserves in states like Montana. After awhile, wildlife photographers started turning up looking for perfect shots of what had become tame animals -- shots they could never get in the woods.
