>I mean of course one should be washing their hands after using the bathrooom

Isn't a large value of washing after using the restroom that it means you'll wash your hands multiple times a day when you wouldn't otherwise?

> but all that other stuff you mentioned.. that's anal to the point of obsessive.

Arguments similar to this were used against washing your hands at all when we first developed a theory of germs and contamination.

Really though, this discussion won't progress until one of us has supporting data.
