for me there is none, I will eventually have resentment for anything I HAVE to do for a living, it's just how my brain works, I would never be at peace at work long-term

Is there such a thing?

I hear some security gigs get pretty boring, not much to do other than stay awake all night for some of them. But maybe that's considered stressful too idk

Cuddler?

Not even unemployment is stress free, but I'd say mattress tester.

That varies. For me, it would probably be some kind of writing that I could do from home or at one of those coworking spaces. It's difficult to label any job "stress free," however, because most jobs I've had have had stress at some points.

Not really a career but a job with little stress is to work as a forest ranger. Am I right?

If you get an answer to this, Saturn. Please let me know. At a guess... I'd imagine being a food taster would be fairly stressless - but requires a rare pallet.
