1. Death during sex has a prototype
While examining the incidence of death during sex, a 1975 study discovered a unique pattern in males: the "deceased is usually married; he is not with a spouse and in unfamiliar surroundings," and death usually occurs after "a big meal with alcohol." Another study in 1989 found further evidence supporting the extramarital sex bit. Fourteen of the 20 cases of "la mort d'amour," or coital death, happened during an affair.

2. You can tell a guy's penis size by his fingers
A University of Liverpool research cited that if a man's ring fingers are longer than his index fingers, this means there were healthy testosterone levels in the womb. If the ring fingers are the same size or smaller than the index fingers, then the male received lower levels of testosterone, implying that one can estimate the length of his organ by the length of the ring finger.
