Weight lifting and bodyweight exercises.

I have a cheap bench press and do a limited amount of exercises once or twice a week. It’s boring and repetitive.

But all those little bits add up.

Even though I’m often severely depressed, I have managed to keep going. I stop for a week or two, but then I restart. And I am reminded of that when I look in a mirror or I catch someone 'mirin. Even now when I’m getting older. I’ll have a better body at 50 than I did at 20. I don’t look like the terminator, but I look better than most guys my age.

I have a couple of degrees, but I’m less proud of those. I sometimes regret going to uni, many people have a degree, being able to study is often a result of luck (parents, money), and it is something young you did. My body is something I have accomplished over years and years of repeated (if small) effort.
