It's fun thing when you slow down and enjoy everything around you instead of just rushing all the time.
Not retired but I do it once or twice whenever I feel exhausted, and want to take things slow.
And btw, you still work a bit on hive, crypto, games etc.😄 Maybe the actual definition is now you do work that you like, and enjoy, and for fun.
I see the fun aspect, not so much the work aspect of Hive, but I am enjoying my self and that is enough.
