This is nothing to spit at.  Saliva is produced in salivary glands.  Saliva is 98% water, but it contains many important substances, including electrolytes, mucus, antibacterial compounds and various enzymes.  The digestive functions of saliva include moistening food, and helping to create a food bolus, so it can be swallowed easily.  Saliva contains the enzyme amylase that breaks some starches down into maltose and dextrin.  Thus, digestion of food occurs within the mouth, even before food reaches the stomach.

An average human produces between 1 to 2 liters of saliva each day, which is a maximum of 730 liters per year.  So, if you live to be just over 70 years, which is the average human lifespan, you will produce a maximum of 51,100 liters, or 13, 500 gallons of saliva.  This is more than enough to fill two swimming pools.
