Breakthrough study in the field of sex-on-the-mind-ology: Men do not think about sex once every seven seconds, researchers at Ohio State University report. They think about sex 19 times a day, which boils down to once every 50 minutes. (Assuming 16 hours of wakefulness and that those horrible recurring nightmares about Great Aunt Ida don't count.) By contrast, women think about sex an average of 10 times a day.

Researchers note that men also think about food and sleeping more than women do.

Female sexist conclusion: Men are desperate cave dwellers who waste all their mental energy on basic needs, while females ponder intelligent things, like the meaning of life.
