If you look at the places where people live longest they are not health nuts especially and have quite a nice lifestyle. eg
>Ikaria, Greece, three times more likely to reach 90 than Americans, almost no dementia
>residents stay active through walking, farming and fishing, but they also make sure to take time out to nap and socialize. In addition to their Mediterranean diet, they eat a lot of wild greens and drink an herbal tea that’s full of nutrients. Their community lifestyle also encourages good health habits and regular social engagement.
Going into a full blown mega health nut phase is not very helpful either because the end result is not going to be pretty anyways.
Now if/when we start making serious life extension progress beyond 120 years with high quality of life then we can start talking.
