Psychologist? Without being ageist :-) I think later in life once you been around the block and got some scars is a good time to be one (of course the formal training and education is 99%) but experience means something. As a bonus you can eventually earn what you were as a developer (probably more in Australia where I am if you are location flexible, for example happy to fill a position somewhere remote)
I think this meets your requirements. It is in danger of AI replacement though. Which would be sad. But reckon there is 20 years of red tape to cut before we get there.
But if you don’t want to talk to people and be on a schedule then carpentry might be a good one. The sort where you make things as oppose to fix architraves in old houses.
AI plus machinery could make “home made” looking stuff but cheapos will keep going to ikea and there will still be a market.
If I didn’t need to make much money and just stay occupied probably do walking tours for free in untouristy places (think the “boring” countryside between cities that ain’t in any guidebooks) or just for a bit of cash walk people’s dogs at the park.
Robots may eventually do these things but to a dog a robot won’t smell like a human so they are the last to be fooled. I imagine in 2050 everyone will have a dog (bred to be small and generally dosile and easy to train) to sniff people for bot detection.
