LOL, well, if someone is spitting on the sidewalk, then you or others might step in it. Not quite the same thing. And certainly in that regard, I agree with you. I was once in Hong Kong and as I walked down the sidewalk, some guy sitting in the doorway of a store, horked a loogie onto my shoe. Now THAT is gross and disgusting.
As for jumping in and out of the water and climbing in and out of a wetsuit on a diveboat, I do believe that guys have it easier than gals in that regard, so yeah, we'll just agree to disagree.

Lemon Mr. Clean or some such is great for soaking of the wetsuit and booties after a dive trip.
