That question is, honestly, kind of stupid. It is akin to asking why eat healthy or why go outside in the sun.

But hey, here we go.

1. Intense physical exercise is the only known way to increase IQ. (Admittedly pure strength training is not the best for this, HIIT workouts are better)

2. Muscle mass is a huge factor in the early death in seniors. Basically people who lack muscle mass are more likely to fall over and fracture something, at which point they are much more likely to die.

3. Lean muscle mass, up to a certain point (e.g. extreme body builders have worse mortality numbers), decreases mortality across the board.

4. I like living w/o pain, and you can choose to either have your joints take the load or your muscles take the load.

5. I enjoy being able to move my body and be active in the world.

6. I'm vain and I like to look good.

> most people don't.

Most people in America die of a heart attack. Most people in America are obese and have troubles moving around. Most people in America don't read books. Most people in America don't enjoy mathematics. Most people in America don't go to art museums.

People should have aspirations to do more than average.
