Saliva is the clear liquid produced by the salivary glands in your mouth. It is comprised mostly of water, but also contains other elements such as electrolytes (for dehydration), mucus, antibacterial compounds, and various enzymes that help digest your food even before it hits your stomach. The chemicals present in saliva also help to fight infections in your mouth and stop tooth decay.

On average, a healthy person will produce about 1 litre of saliva a day. There's 365 days in a year, so that's 365 liters per year which equals about 96 gallons. The average American lives to be about 75, so 75 times 94 is:

The average human produces a little over 7,000 gallons of saliva in their lifetime.
