Outside of the obvious things you can do (or shouldn't do) for your health, it kind of comes down to genetics and luck.

Remember Pope John Paul II in his final years, about as infirm as you can get short of actually dying? He lived a pretty healthy life, was known as "healthy" when appointed (which stood out as several of the previous popes had health issues), but was "only" 84 when he died and suffered from serious health issues ten years prior to his death.

Meanwhile Marshall Allen is still playing shows at 98. Yes, ninety-eight. It ought not be possible but somehow it is. This seems to have been recorded last month: https://www.youtube.com/watch?v=0M1Ndcy_ZQE
