And what about those of us that find they have stretches where they don't focus well on anything? Games included. There are several games I'd like to spend a bit of time on. It ain't happening.
Exercise is annoying, as without a lot of modern life, it largely takes care of itself. Back when I could just walk to a grocery, as an easy example, it was unsurprisingly easy to stay in decent shape.
My problem is typically more that there are plenty of more interesting things to do than anything I'd like to do right now.
