I was always interested in the question "to what extent is extending the life of an individual through technological means considered ethical?" That is to say, are human beings trying to extend our lives beyond what the natural biological timer allows ethical or right?
I just had a lecture on lives and immortality and it got me interested. For instance extending our lives through medical treatments I think is fine, however trying to live beyond what is allowed of us, does that mean we get to play the hands of the god and control our own destiny after what is permitted? I am just very curious on the ethics behind cryonics or other means of extending the lifelines of an individual through artificial means after the normal lifespan permitted.
I would appreciate the feedback and ideas.
