What confuses me is that they seem to be making the assumption that if they are able to give good health in the later years, that the person will die at the same age they would have. Which seems unlikely. Seems to me if they are in good health, they won't die (healthy people don't tend to). Eventually, though, they will be in bad health enough to die. In which case, it IS about longer life spans, since we'll still have the same problems, just at a later age. I'm all for longer life (and I imagine they are too), but it seems to me that they are just trying to be politically correct by saying things like the above.
