> It's hard to identify any downsides but the upsides are tremendous.

I wish! If you're lucky (or not particularly unlucky) that might be true.

I don't feel any mental benefits, nor do I sleep better. Fun kinds of exercise (badminton, football, BJJ) always seem to injure me me over longer time periods (and it takes months, or even years, to heal when you're in your forties). And they are not very forgiving, schedule-wise.

Lifting weights or rowing on a machine is painfully boring, but it does make me feel better physically. It's a great upside, but the downsides are real too.
