Interesting articles, sure, but I wish you'd addressed societal and generational impact (you can skip overpopulation concerns).

Sure, we age because the world changes, but in case you haven't noticed, the rate of change in the human world is accelerating. It strikes me as a bad idea to bet on trends that are on a collision course by their very nature. Maybe there is a way to reconcile extreme longevity with human society, but if there is, I sure haven't heard it or found it on that website.
