Each day, on average, humans produce one ounce of excrement for every 12 pounds of body weight. This means that the average man produces about 360 lbs (163.293 kilograms) of excrement per year. We also urinate the equivalent of 132 gallons every year, and produce 60 gallons of sweat.
The average person also has eight to twelve pounds of faecal matter putrefying inside their body.
This is nothing compared to the elephant, which produces 20 kilos of dung every day!
