destroying their lives and their bodies.

I don't mean any offense Destiny, long time fan/lurker here, but this is something that really irks me. Is this not true? You don't think these Korean gamers are destroying their bodies and atrophying their muscles by sitting 10+ hours a day playing video games? You are doing the exact same thing, so it's no surprise you rush to the defense of such a lifestyle. I'm not even going to get into your terrible diet and its consequences.

I feel like this is something that is common sense, but here's some sources if you'd like:

These data demonstrate a dose-response association between sitting time and mortality from all causes and CVD, independent of leisure time physical activity. In addition to the promotion of moderate-to-vigorous physical activity and a healthy weight, physicians should discourage sitting for extended periods.

Even when adults meet physical activity guidelines, sitting for prolonged periods can compromise metabolic health. Television (TV) time and objective measurement studies show deleterious associations, and breaking up sedentary time is beneficial. Sitting time, TV time, and time sitting in automobiles increase premature mortality risk.

At work I have a convertible standing desk (which allows me to stand for most of the day and works my leg muscles) and I make sure to exercise at least 3 days out of the week. You're still young, it's never too late to start taking care of yourself.
