Let me start by saying that I haven't read the article or the study, but I would be very suspicious that this could stop, slow, delay or reverse cancer. In fact, I would guess that it would actually cause more cancer. I hope I'm wrong.

We would also have to consider the impact of people living longer would have on the environment. People will still be having kids, and if you were going to live longer you might want to have many more kids while you're young. Our rock is going to get pretty crowded really fast if people stop dying of old age.

Then there's the point about people still being 'productive' to society. Honestly, if I'm going to live longer, I don't want it to be so I can continue to be productive. I don't like being productive as it is. I'd prefer that humanity focus first on fixing our economy before trying to extend our lives.

Despite appearances, I'm not trying to argue with you for the sake of argument, but more just putting other ideas out there to consider. I do hope your vision is right, and this will be something available to everyone and helps to make our final years more pleasant.
