There is a very large, addressable, and under-appreciated factor is delayed aging: Stress reduction. Study after study, as well as pervasive anecdotal observation, demonstrate the role of stress in aging and deterioration. Unfortunately, reducing it for someone often means getting someone else to give something up (wealth, convenience, exploitative predilections, etc.). And so far, we've not been able to maintain such social cooperation where it has been established. Personally, a large factor in my life has been noise. I've had some incredibly inconsiderate neighbors as well as some rather ignorant and counter-productive employers. That's just one example -- anecdote. But studies continue to roll out documenting links between chronic stress and physical as well as mental deterioration. And "everyone" has observed a family member or friend rapidly look much older while and after going through a crisis. On a personal level, I'd recommend that people remove themselves from out-of-their-control stressful situations at the first opportunity.
