Giraffes often sleep for only 20 minutes in any 24 hours. They may sleep up to 2 hours (in spurts - not all at once), but this is rare. They never lie down.

Your body makes about two pints of spit every day. There are glands in your mouth that produce the spit. Spit is mostly water but it also contains chemicals that kill germs and pre-digest the food that you eat. There's also a little bit of urea and uric acid in it (same stuff that makes urine or pee). Spits biggest function is to help you digest the food that you eat. It also lubricates the mouth making food easier to chew and move through the throat to the stomach. As the spit dissolves the food in your mouth, chemicals are released onto your tongue. The taste buds on your tongue detect these chemicals and send a signal to your brain about the taste.
