I don't know about you, but the dentist bike expression is starting to sound like fingernails on a chalkboard to me. Holding dentists up as the quintessential high earners with all the best gear and none of the skills is seriously about a generation old at this point. Yeah, dentists generally make a comfortable living, but they're far from the top of the earnings scale these days. And in fact, most of the dentists I know don't mountain bike or do so minimaly because their hands are their livelihood, so they're pretty interested in minimizing the risk of injury. I suggest deleting the "dentist" part of the expression and inserting "PE guy", "cryptobro" or "VC dude", so least the earnings reference part of the expression will be appropriate for... this century.
