ACT: The answer to that, very obvious, actually: Preemptive medicine. The best way to take care of an illness is to make sure you don't get it in the first place. This attention to health should not just be a personal thing, either. When people do things as a group, they have more motivation to stick with them. For instance, in Japan, they have this thing called Radio Taiso, or just Radio Calisthenics. People get together as groups (mostly companies nad schools) and do several minutes of calisthenics as a group in the mornings. This jump starts your energy for the rest of the day and lets you know that there are other people invested in your health as well. Plus, its fun too! Wanna see just how much fun Radio Taiso is? Why not take a look yourself?
IMAGINE: In a perfect world, everyone would be exercising several times a day and would be eating all homemade foods. Not only that, but healthy living wouldn't just be something people did a few times a week. It would be a way of life. People would walk to work and school and shopping. They would spend more time around time with friends. The less people isolate themselves, the more they'll feel connected to others. When people feel connected, they feel like they have a reason to stay healthy.
