Stats are just stats and can be manipulated. The ratio always changes. Sometimes it's 1 in 4. Other times its 1 in 6. Right now
The Complete Herpes Information Center says it's 1 in 5.
Any way you cut it, I should have herpes many times over by now. But I don't. Not even oral herpes. And I've shared joints, pipes and bongs with a LOT of sketchy characters in my younger days.
