Also, everything here is super-sized. Plus, you can gorge out at 3:00 am. I lived in Austria a few years ago, and was amazed how impossible it was to get a cheap bite to eat after, like, 8:00 pm.
We also love our cars too much and are prosperous enough that we pay housecleaners, lawncare pros, carpenters, etc., to do physical jobs that we would've done ourselves a few decades ago.
And the internet/info age is just going to make it worse. Twenty years ago, if you needed information on something, you had to go somewhere (library, post office, store, etc.) to get it, which sometimes involved some form of physical activity. Now it's just click-click-click.
