This cannot possibly be right. Even I don't go there 51 times a day, that would be almost 2x/hour, and in two hours I will be a 73 year old man.
So I went to Cottonelle.com. There I found, "Most people use the toilet about 51 times a day, but anything in the 4-10 range is deemed 'normal'” so it is clear they mean 5.1 times a day, which at least is between 4 and 10. What it would mean to use the toilet one tenth of a time escapes me though.
