Ask HN: Anyone Codes as a Relaxation Exercise?

I noticed this last year. When I'm very stressed or very tired I find myself coding as a way to relax. It's not regular work, just small toy code, exploring ideas or technologies. I never force myself to anything with this projects. I stop whenever I want to stop and if I want to give up I just do it without any guilt.

I've been thinking why I do it? I think it's probably the little worlds of code I create and that I fully control and the pleasure of all the small accomplishements.

Does anyone else out here does this? Would love to hear it.
