And did you have the same feeling with them than I had with 90' old people? That is, seeing most of them sick or handicapped to the point they could not achieve much? Obviously, this would not be proof : even if we accept the hypothesis that present day old people are indeed more capable than past ones, and it's not just an interpretation from me, for all we know it can be just healthcare progress or easier lifestyle. It would be interesting to find out how old people were seen before world wars, if they did any better than their children who fought them. The fact that such event could have lifelong impact does not seem far fetched, though, it could be an interesting hypothesis to test. If anything, it could help prevent preconception against old people who did not go through such events.
