Nice post and subject for discussion @sauravrungta. I think like you say, the question is, is it moral? Would we really want to take take up space that the next generation so desperately needs?
And think about it, if you have privileged life, by the end of it you have either seen and done most things that you wanted.
If you have a life full of struggles and misery... why the hell would you want to extend that?
I would say no to eternal life. Just do the best with the life you are given and be done with it.
Beautifully put. Make the best of what you have right? :)
