Life is too complex for us humans to understand, we are just scratching the surface. There are too many confounding variables. Smoking has been proven to kill but has not smoking been shown to improve quality of life and longevity for the SAME individuals who died of smoking? There are multiple variables at play: smoking kills animals in a lab but what about depression and stress which otherwise be reduced by smoking? Some people are not prone to such problems or have other ways of dealing with them so smoking would just kill such people. But for others it could improve their quality of life or even longevity. Same goes with the idea in this article: travel less to stay healthy? Many would argue that life’s purpose is to travel and make memories, life would be meaningless for these people. Don’t take night shifts to live longer? Easier said than done if not taking night shifts means you and your family go to sleep hungry or you have to take a dangerous day job. It’s great that we are learning more about this terrible disease but extrapolating the findings to universal lifestyle choices is nonsense.
