I went to the mall recently (big mistake) and I had to get lunch at the food court. I don't think there was a single gram of fiber across the 10 or so restaurants. So much of America is drive-thru garbage. Yup -- you don't even have to stand up to get your Big Mac. You can endanger other people by eating it while you drive.
We tell people to get exercise and then force them to have 9-5 desk jobs that have a 45 minute car-commute each way. And what's so much worse is that people are paying a ton of money for that car that's slowly killing them. It's not entirely their fault though -- that's just the way our society is set up. Walkability is a luxury only the rich can afford.
Then, 20 years later you show up to the doctor and the standard course of action is to prescribe a bunch of medications. The doctor says "you should exercise more and eat better" and many people just don't.
So much is broken.
