Prof. Terri Fisher of Ohio State University disproved the cliche that men think about sex every seven seconds. She asked 163 students of both sexes to carry a chart and mark down everytime they thought about sex, food or sleep.  The results?  Men think about sex about once an hour but think about food and sleep much more frequently.  And they think about all three - sex, food, and sleep - more often than women do.

- Well, duh!

- The women in the study said they were just too tired to think about sex or food.  

- Charlie Sheen doesn’t think about sex once an hour, he has sex once an hour!

- Men usually go for the trifecta:  Sex, a sandwich and then a nap.
