I like your list, very much. I would add television, video games, and other "indoor entertainment" especially as/when aimed at young people who, in my generation, would have spent the majority of their childhood out-of-doors-- playing, fishing, hunting, camping, playing sports, beating each other, what have you...

One of the greatest evils when it comes to health is inactivity, and we are the most static society in the history of the planet, bar none. It is especially dangerous to the young, who thus begin life with unhealthy patterns and habits that can contribute to obesity in a big way. Once obese, even less activity usually occurs, and the young person just contiues to spiral downard. So sad.
