Why would you be almost incapacitated at 70+ years old? Most people get like that only because of poor diets, poor sleep, lack of physical exercise, and a shit lifestyle in general. You're a Zevist. Take control of your life, and you'll be better off at 70+ than most people are in their 20s and 30s.
Loss of ability is purely habits-related. It has nothing to do with aging. Carry load (getting at least to carrying your body mass in load), keep doing it forever, and you'll still be able to do it at 80+ year old. Squat or twice a week, and you'll still be able to get up and down several flights of stairs no matter your age. Run a few times a week, and you'll still be able to walk fast no matter the age. And so on and so forth.
Age is about what habits you collect throughout your life. If you make it a point of collecting weakening habits, you build momentum toward becoming weak. If you make it a point of collecting empowering habits, you build momentum toward being strong. Simple as that.
My grandma for over a decade decided she wanted to be stupid and only ate bread and cheese for every meal (sometimes ice cream), no exercise, and smoked a lot. Guess where she is now? Brain atrophy and in need of a care home because her needs are beyond what family can provide (i.e. she needs specialised care and 24/7 surveillance). What brought her there? Her habits, and ignoring my continuous, respectful warnings.
Meanwhile you can find people at 70+ who can still do artistic gymnastics, or bodybuilding, or crossfit, or wahtever, and live independently. Why? Because they invested in the right habits, instead of making up excuses and being stubborn.
Then you also have me. I won't disclose my age but I'm fitter than most gym people and so-called sports enthusiast (i.e. not the real athletes) in their early 20s. Why? Because I'm doing what I'm supposed to do: following a path of growth, rather than a path of decay. As a Zevist, this is my duty as much as it is my duty to meditate, and so on.
And I'm not saying this to boast my ego. I'm telling you because it's achievable, and it's the right path. Nobody wants to be disabled when they're old, but you need to put the work in for that to happen, not delude yourself that it's fate, inevitable.
I would advise against getting ahead of yourself and thinking of suicide. You're not 70+ years old. Your life is now, in the present. You don't need to plan in advance for something that is subject to change. Instead, build your future through making your decisions now and living in the present.
Why is how you'll be at 70+ years old something to think about now? What's the rush?
If you want to think about how you'll be when you're that age, visualise yourself strong in body, mind, and spirit, independent, and happy. Somebody else tells you otherwise? Ignore them, or prove them wrong by becoming the polar opposite of the weakness they try to project on you. The disillusioned and defeated don't get to tell a Zevist what their future will look like. They're incapable of that. They're ignorant.
