Ask HN: What fun/useful things do you do when tired, instead of Netflix/Reddit?

After I get tired at the end of a day, I tend to waste my time doing pointless things - watching Netflix, refreshing Reddit, etc.

They are not productive and bring me no joy.

I'm looking for something fun/smart/useful/relaxing/healthy to do instead of that, something that doesn't require a lot of focus, mental energy, or will power.

Can you recommend something like that?
