YMMV, but a significant amount of real-world and statistically significant contributions can be made to average human longevity by focusing on paths of least resistance, such as tackling gun and car related deaths, then on the individual+average longevity by looking at preventable-but-chronic conditions (such as diabetes) by regulating things like common pollutants, added sugars to foods, and having better access to the outdoors and exercise/activity. Then you can enjoy a long life that will - on average - be healthy and long enough and with decreased risk of dying early. Past that, a lot of the research feels like “solutionism”.
