Humor And Testosterone

Professor Sam Shuster, an English physician, decided to ride his unicycle down the streets of Newcastle upon Tyne. As he rode, he recorded the reactions of people who saw him. He found that most women made encouraging remarks. Most men made jokes.

Men tend to make more jokes than women, Shuster says, and men make jokes that are more aggressive than women's jokes. Dr. Shuster says the easiest explanation for this lies in the male hormone testosterone.

All of Dr. Shuster's observations about male and female humor can be found in the lastest issue of the British Medical Journal.
