Edgar, I too hope to prolong my life as long as possible--in order to do more of the things I love to do. For that reason, I eat VERY well, exercise, meditate, etc. etc.. I DO wish I could live for another sixty years. I could do and experience SO much. My wife often anguishes that she is running out of time. She lives to appreciate philosophy (especially Nietzsche and Schopenhauer and their commentators), and there is so much she hasn't gotten to yet. I want to develop my painting and music skills (my hands are not what they used to be for the violin: that's tough).
But, you know, while I appreciate my life and, as such, would prolong it as much as possible, I also appreciate, with a religious fervor, the Universe of which I am and have always been a part. I, JLNobody, will die in a few years, but, I do feel that my true self will never end, just as it never began.
Sorry to flip out on you.
P.S., I would advise young people to accomplish all the things they might like to do and achieve. The best solution to the "problem" of death is to have lived a full life. And don't forget to love and permit yourself to be loved.
