well if you count your turds in one day which is usually 2 turds to every person but if you then count the over weight and obese people which stands at around the 1 billion mark then you have to say that they drop a crap at least 6 times per day. sooo what have we got 7 billion turds times 2 is 14 billion turds then 1 billion turds times by 6 equals 16 billion turds put them together is 30 billion turds and now to your question.
