Did you mean indefinitely - or did you mean infinitely?
If you meant infinitely - I remember seeing one of the Marx Brothers years ago accepting a lifetime achievement award from the Academy. A withered old man - remnants of his former self, hobbled on stage almost unable to make it out there without assistance. He thanked the academy for honoring his work, stating that he was flattered. However, "I don't know you. My colleagues are gone." It was very moving - and illuminating.
If everyone you love doesn't make that same choice - to live indefinitely, it's just possible you might not want to go on living after they are all gone.
Something to think about.
And, if you meant indefinitely, there are women all over the world who have had hysterectomys - and are no longer able to bare children. The tradeoff was not indefinite life, just a more comfortable one - and it was still worth it! There are also many patients battling cancer who have opted for treatment to save their lives, sacrificing the possibility of having children - and they have done so.
Forgive me, but I don't see the point you are trying to make.
