http://vitals.msnbc.msn.com/_news/2012/01/03/9917514-real-benjamin-button-stem-cells-reverse-aging-in-miceCN: Scientists have been injecting mice with their own stem cells and their aging has drastically slowed. They see this as a huge potential on human use eventually.
It's amazing what science can do. Assuming it was FDA approved and didn't have any side effects, would you do it? Would you inject yourself with your own stem cells in order to live to be healthy, say, 200 years old? If given the option, would you live forever?
I definitely wouldn't want to live forever. Living to be 200? I'm not sure. It'd be awesome to live that long, but I feel like I'd be ready to pass on by then. You'd also have to work for over 150 yars of your life I'm guessing in order to financially support yourself.
