In my country people both believe and have some evidence that those that live in an orderly fashion, learn to be emotionally detached and focus most of their energies on flow states and forward escapes end up living longer than those who don't and living beyond 100 is not really difficult if one lives a healthy balanced life as prescribed by Yoga philosophy from the get go.
I'm gonna stick my neck out and say that if life's goal is living, like it should be — and not endless economic growth or an endless compulsion on the hedonic treadmill — it isn't hard to live beyond 100.
When life's goal is living every aspect of it from family, to children to rest get the love and attention they deserve and economic outcomes and status games do not dictate life. But for that to happen one needs to realise that the most precious thing they own is their energy and will. And must learn to see which activities increase their leverage and which ones don't. When one lives that way, the most contrarian thing is that you can achieve a lot more than by chasing because you start to intrinsically do rather than chase — the latter being much more expensive energy wise. I understand if this gets too esoteric for HN. But it's what I believe to be true and is also IMHO the reason why many high performing individuals seem to be unaffected by illnesses even at old age because their energy is continuously and exponentially directed in virtuous cycles and not disturbed easily by external happenings. You are energy and can be understood and defined entirely mathematically. Yoga means union with the universe's synchronicity. It originates from Sankhya Philosophy which simply means counting all energy.
