If there was a pill to cause aging to be cut in half? i.e. you could live twice as long if you started taking it as an infant, would it be a good thing? If women could reproduce into their 70’s and 80’s would it cause the earth to over populate sooner? So if I’m 50 and would have lived to 100 without the pill, but with it could live to 150, would I want to? I think as long as the answer is “yes” then one is still alive and life is worth living, if one does not want to take the pill then one foot is already in the grave.
