TRIVIA: Do you know why Giraffes don’t get lymphedema?

Physiologists have discovered that giraffe skin is inelastic, meaning that it does not stretch like the skin of humans.  Therefore, the world’s tallest animals are not susceptible to health projects like lymphedema and venous disease, even though they may be on their feet for 24 hours a day!  (They only need about 2 hours of sleep and often do that while standing!)

The giraffe’s skin has also been studied by NASA in research into gravity suits.  Interesting, eh?
