As a former flight attendant I can attest to this. If people knew how often their pilots used the cockpit O^2^ to cure hangovers there would be a lot less people comfortable with flying. At least in the US, that is. I can't speak for other countries.

I dunno if you're being facetious, but it's their entire personalities and all they talk about... In my experience, in general. No offense to pilots who don't do this. How people describe marathon runners and vegans.
