Not me but a friend. PhD in Physics and programming, he did a ton of modeling with R. He had/has chronic health issues, so used that to get a teaching job in a country with socialized medicine.

Once he got citizenship he'd had enough of the academia and coding... dude changed to cheese making. Like, he is a full-time cheese consultant now, and travels around the world to assist in cheese making efforts, setting up cheese caves, etc. Does a bit of other culinary stuff too, occasional pop-up restaurants, etc.

I think about that a lot, especially when I have to sit through change control meetings that go nowhere...
