His argument is that there would be overcrowding. Then, we potentially wouldn't be able to sustain the large population... then people would die from lack of food/water. This can probably be overcome with new technology, much like in Asimov's robot books (the "Cities"). Anyways, while death from old age is sad, I think premature death is worse. The 5 year old kid with leukemia, the car accidents, wars. There are tons of things that kill people before they can live a "whole life" which I think we should work on first (not that we can't do both). Hopefully with some of these aging technologies, quality of life for the 'elderly' would also improve. I would hate if I couldn't play sports for 90% of my life.
