I don’t think it’s necessary to compare yourself to others here. The consumption goal should just be to consume less and every effort makes a difference. If you eat red meat every day, then try every other day. If you already do that, try once a week. If you feel you can consume even less then have it as a rare treat or just cut it out entirely.
I work at a hospital and most of the patients there are definitely older than dirt people getting surgeries just to extend their life a few years or even months. Most of the time it is family members making those decisions because they don’t want or know how to say goodbye. We have had patients that effectively died, but the family insists on keeping their organs alive with machines in the hopes that they wake up.
As for the meaning of life? I think it is 100% to entertain ourselves until death. Even if there was a greater meaning created by some deity, we’re probably not able to understand it anymore than a donkey could understand calculus. I personally could never trust any human to tell me who or what god is and/or wants. And god has yet to reveal theirself to me…
