I'd agree. Frequency and intensity, aerobic or strength, all matter too.

My mom walks for 30 minutes a day, while I run rather fast for the same time. I always tell her she should run a little, but she doesn't like to sweat.

Granted, 30 minutes of walking is 100x better than sitting around, and running is ~5x better. I'll give her that. Lessening returns and all.

My mental model is "easy" activity is sufficient to not die when you're 60, and more intense stuff will make you thrive into your 80s.
