Is it a red flag if a man is a Rolfer?

He’s a part-time Rolfer and full-time history professor.

Academics in my city are not highly compensated, so I imagine he Rolfs for the additional income and because he enjoys it.

I'll add that most professors (including tenured faculty) in my city have some sort of side hustle because they don't earn a ton of money from their academic jobs. But I have never met a professor whose side gig is Rolfing.
