The healthiest people in the world tend to live and eat a certain way. Following habits of healthy people is a good place to start in learning how to be healthy yourself.
According to this infographic, the healthiest people in the world tend to have less stress and tend to eat a more natural diet with fresh foods and less processed foods. Healthy people also tend to have a strong social network and a strong sense of purpose.
See, it’s not so tough to be health. Just eat natural foods, get plenty of sleep, enjoy other people, and be motivated. But yes, you do have to choose to be healthy. And you have to want it enough to buck the trends of modern society (cheap, convenient, processed foods and sedentary forms of entertainment).
