A Person Produces 25,000 Quarts Of Saliva In Their Lifetime
In one lifetime, a person produces 25,000 quarts of saliva. That is a lot of spit! But let us put it into perspective so you can understand just how huge that amount of saliva is. Twenty-five thousand quarts is enough to fill two average-sized swimming pools. So, if the saliva you have produced in life had been somehow extracted, it would serve two pools.
However, the saliva is mostly recycled instead of produced. This is because human beings are constantly swallowing and absorbing saliva. Your body takes in about 30 ml of saliva in an hour.
