@Salamanderwizard There's a popular myth, especially among moralist conservatives, that you have to have done something they'd disapprove of to catch it. You don't. It's enough if, say, your dentist's hygeinist wasn't thorough enough, or if you used someone else's razor. The vector of transmission is unknown in fully 1:5 cases. Meaning, so far as we know right now, just about anyone can get it, no matter who they are or what they do (or don't do).
