I've read/watched alot about anti-aging research over the past year, and while the topic is very interesting, I still can't understand why people are researching it. As far as I know, bassically every place in the world has a growing human population besides Africa and perhaps China (and only because of the 1 child policy). Even with AIDS, cancer, terrorism, all sorts of various diseases, global warming, the hole in the ozone layer pollution etc. the world's human population is still growing, and in most places, average life spans are increasing. Yet these scientists are still trying to find ways to make poeple live longer and longer and longer. Of course when you look at it from an individual perspective, you might want your beloved parents to live healthy lives to 160 years old, but imagine a society with people living for that long, it would be so ridiculously over-crowded. Just to keep the economy going the retirement age would keep having to be raised, social security would either fail or take ridiculous sums of money from workers, there'd be huge amounts of trash, more and more and more cities would have to be built, oh god it would all go to hell. Bassically, what I'm saying is, let old people die.
