I've never seen the show and am by no means a teetotaller. However, if I am diving or have recently been diving, I will rarely drink alcoholic beverages. I'm a "mature" diver and I don't wish to add additional DCS risk (although I've never yet taken a hit in nearly 48 years of diving).

It's hard to comment on a show I've never watched, but if alcohol is as prominent a fixture as the OP indicates, those involved are people I'd be highly unlikely to dive with. However, if I'm NOT diving, I might drink with them.
