Until I was about 7 or 8, I used to believe that when you got to be 40, you suddenly changed into an old person who had lots of wrinkles, loose skin, flabby arms and legs and grey hair (for women) or was bald (for men), and needed false teeth, glasses, lots of medications, and adult diapers. I also believed that when a guy turned 21, he would suddenly grow a mustash and that it would completely grow back overnight if it was shaved off.
