Playing sports instead of watching.

If all of the adults in America who watch baseball and football instead PLAYED baseball or football in an amateur adult league, there would be a huge glut of doctors in America instead of a shortage.

Why is it that watching sports is so popular, but playing them as an adult is something that is seldom done? Playing sports is super common for kids, but then we grow up and sit on the couch in front of the TV. That is really quite unfortunate.

Physical activity is crucial to mental health. In fact, I've read published studies that show that exercise is as effective as an SSRI at combating depression.
