People keep fussing about the problems of overpopulation etc, without realizing the core of the issue. It isn't because we like to have sex more or because we are more fertile now - it's because of modern medicine, we live much longer.

By researching such technologies, overpopulation will become more of a problem and more radical approaches need to be taken.

Life extending tech may also be quite expensive, meaning that there will be a whole new form of upperclass people, who will stay in power for far longer. Rich dictators will look at such technology with glee.

While I'm for the other side, I'll try to help you out.

Obviously it goes against nature, we were made to live that long, so why fight it? Also, just because we can live longer does not mean we will actually live. For example,prolonging a life of someone who is bed ridden seems pointless to most people.

I believe we live for a reason and die for a reason. Nobody deserves to live forever. Plus have you seen people that live to be like 100? They can't walk most the time or move barely at all. If I live past 90 shoot me. lol

Life is a awesome but think about it. When you get old your bones get brittle and you slowly fade away. Prolonging that would probably suck. Unless we could find a way to prolong our youth, our health then that might be helpful. but then again it would be harder to get 'out with the old and in with the new'

Humans have a given time that they should live.. i think we should let others live. Just like saurbaby said, living doesnt just mean that you are really living your life. Youre just alive, and yet, you dont get the best of anything.
