Ever notice why the oldest people in the world are often from Japan?
It's no coincidence that the Japanese live longer than everyone else on Earth, and that their diet and lifestyle are relatively healthier too. The average Japanese person eats 25% fewer calories than the average American, which is partly why they have the lowest obesity rate in the developed world. While you may be thinking that they naturally have good genetics, their health is contingent on the fact that they eat small meals filled with relatively healthier foods. Life is already short, so why not make a few healthy diet changes and strive to live to 100!
