Suzanne - that's a rather different question, but I think the answer would still be 'no'. Especially if the reason for seeking eternal youth would be mostly cosmetic. One would still be living a lie, and it would be grossly unfair to future generations, and disastrous for the planet as a whole. I don't think I'd have the right to do that. Others may think differently, of course. Am not criticising them.
The rest of this is probably going to sound far too serious for a S and B thread. Please forgive me, but here goes:
People in the past believed that men and women can and (sometimes) do gain wisdom or compassion or understanding as they get old; they (hopefully) can learn from long experience. I hope that's true. Because that is surely what matters, not looking other than we really are. By all means, let's look our very, very best, but be true to ourselves.
Yes, I know, and am grateful, that wonderful medical advances have lengthened lifespans and - even more importantly - done a great deal to end suffering. But still, so far, only for a privileged section of humanity. It would surely be better to try to extend good health care to everyone, worldwide, before seeking eternal youth for the few.
