The irony is that, at least in my social circles, the stereotype of the "software developer who does rock-climbing" is really a thing.

To the point where, because part of my identity is being a hipster who is not like everyone else, I tend to avoid rock-climbing unless it's with friends, and when people ask me what sports I do I tell them I do Olympic Weightlifting, because it's actually somewhat original, even if, in practice 90% of the people at my Oly lifting club are either sports coaches or engineers :P
