The amount of liquid a person produces in a lifetime can vary widely depending on various factors, including age, health, diet, and individual physiology. However, I can provide a rough estimate based on certain bodily fluids that the average person produces throughout their life. The average man produces in a lifetime 35,990 liters of urine (42.7%); 25,977 liters of saliva (30,8%); 16,236 liters of sweat (19,3%); 5,954 liters of tears (7,1%). and 81,5 liters of sperm (0,1%). Below is a fascinating infographic created by Presium.pro shows how much liquid the average man produces in a lifetime. With a human life expectancy of 75-80 years, these numbers would look as follows: Saliva: On average, a person produces about 1 to 1.5 liters (approximately 34 to 51 fluid ounces) of saliva per day. Over a typical lifespan of around 75 to 80 years, this could add up to roughly 27,375 to 43,800 liters (about 7,233 to 11,569 gallons) of saliva. Urine: An adult urinates about 1 to 2 liters (a
