Saliva is good for many things. It wets your food as you chew and makes it easier to swallow. It helps taste buds do their job and assists in digestion. Saliva is also cheap entertainment when there is nothing better to do. Learn to blow saliva bubbles and entertain yourself and your friends with nothing but the spit in your mouth.
