Ask HN: Job for someone burnt out on tech?

I'm a developer of 10 years. Lately, I cannot bring myself to sit at a desk, let alone work. Vacations temporarily help, new habits, etc. But I'm just done with it. My job is great, the problem is with me.

What would be an ideal non-sedentary job for someone with no other professional skills, but who only needs to cover living expenses of a modest lifestyle. No debts children etc.

My dream job is a groundskeeper of a park. What about you?

Thanks.
