Just so the message is not lost: Any odds may seem negligible until you catch it.
Also as mentioned in JS's OP and in Free2Fly's post above, being drunk or stoned and around scuzzy women is a recipe for disaster.
It used to be that a diagnosis of HIV was a death sentence. In the last several years in the developed world, its more like a chronic condition for many. That doesn't make it any less of a tragedy, and any less devastating to to one's self-image and view of the future -just "less physically lethal."
If you think the chances are negligible, then you have not read up on the subject enough, or you have not lived though AIDS with a loved one (yet).
Be careful out there.
Thanks again, JS, for the reminder. It can happen to anyone, even those who aren't punters.
