My personal stance has always been to act on the assumption that everybody is HIV+ and act accordingly.

Funny, I'm a motorcycle guy with two variations on the crotch rocket theme that I ride fairly aggressively on the street, and also do light racing and trackdays. I categorically refuse to do thing in bed that might - emphasis on might - make me sick or die in 10 or 20 years time. But I'll make 10 or 20 instant decisions in the course of a ride, any one of which could cripple or kill me if I got it wrong.

People's perceptions and management of risk are wildly at odds to what risk truly is. I've got a fascinating article ("The Science of Danger") downloaded from BIKE magazine, if any motorcyclists or adrenaline junkies are interested pm me off list. It's a pdf so it's not uploadable.

Cheers, Have a great weekend one and all.
