This is a great question for those of us in the US. Our diets on a whole are so poor, that 98% of us won’t be around to even partake in that discussion. Although diet and genetics have a great deal to do with longevity, stress plays a major role in our society. Earning great amounts of money rather than loving families has become the value system of our country. This video is a perfect example of longevity and some of the elements it takes to get to that point. Although most can’t, it is something to strive towards. Enjoy the video. If I find the whole documentary, I will post it.
