Student feels sting for science

Throughout history, a select band of the brave has willingly turned into human guinea pigs in the cause of science.

Benjamin Franklin got a shock from lightning by flying a kite in a storm. Sir Humphry Davy discovered laughing gas was an effective anaesthetic and Albert Hofmann took the first LSD trip in his search for new medicines.

Now, an academic has deliberately subjected himself to weeks of pain to answer one burning question - just where is the worst place on the body to get stung by a bee?

Michael Smith of Cornell University in the US was unstinting in his dedication to the task with even the most delicate parts of his anatomy subjected to multiple stings.

The results, published in the scientific journal PeerJ, could shed new light on the human body's sensitivity to pain in general. Smith, who researches bee colonies, said the idea came to him after a chat with his adviser about the occupational hazards. "We speculated it probably really would hurt to get stung in the testicles," he said.

"Two days later, by chance, I did get stung there. It didn't hurt as much as I expected it to."

And so a science project began. After choosing 25 locations on the body, Smith grasped a honeybee in forceps, placed it against his skin until it stung him, then allowed the stinger to remain for a minute - five times a day for 38 days.

The results were not quite as expected. Smith, a graduate student, rated his experiences with marks out of 10, compared with a control sting to the forearm which was given a five.

The testicles turned out to be the fourth worst place with an average score of seven, equal with the cheek, palm and armpit. The sorest place, the nostril, was much worse - he rated the experience as a nine - followed by the upper lip on 8.7 and the penis some distance behind in third on 7.3.

The least painful locations were the skull, tip of the middle toe and upper arm, all rated at 2.3.
