The article is targeted at people who sit for long periods of time. It says nothing about how much they might exercise or not. In any case, I don't do 22 minutes of exercise a day, more like 2 minutes.

So I'm still the target audience, you're wrong, and I'm not right, because I wasn't trying to make a point or win Internet Argument Points.

Why does every comment on HN need to be adversarial? I feel like it's a result of the rules being skewed to only comments that are "useful", and that leading to intellectual competition and constantly trying to "win" some point. Why can't we just share our thoughts without constant corrections?
