Unusual Side-Hustles in Medical or Wellness Fields

I’ve come across some pretty unexpected ways people are making extra cash that still connect back to health or medical research.

Has anyone else stumbled upon something like this, maybe even in their own field? I’d love to hear about other unique gigs that have a surprising link to wellness or research.
