Ask HN: Is there such a thing as an ex-programmer?

Due to terrible job market conditions (and tendinitis) I've been considering changing careers. But I've been writing code since child and can't imagine life without programming. I wonder if I'll still write code for fun even if I find a job in another industry. Is there anyone who wrote code for 20 years straight and then suddenly stopped, never done it again and got rusty enough to say you don't know how to do it anymore? Is this a thing?
