The Ink-Pot and the Palette

I'm getting stuck on his assumptions that everybody who might benefit from more exercise could just spring for a bike or a skateboard, that everybody has a job that's close enough to their workplace to allow for skateboarding there, that nobody works two or three jobs or works night shift or has to run errands with their three small children and maybe can't ride a bike, that everyone has the time after their third job to exercise if they only had the willpower, that no one has physical or mental health concerns that are barriers to skateboarding, and yes, the ones you listed about fat=lazy and active transportation=magical cure-all. He's making so many assumptions it's hard to parse.

Possibly the issue is that he's not actually discussing the topic? I mean, he's not talking about the benefits of active transportation, a phenomenon which promotes exercise, he's talking about working out.

Argh, I don't know. Hopeful my thinking out loud will spark something for you.
