Huh?
The average lifespan back in the days of implementing Social Security was 62.
People are definately living longer than that nowadays.
We're talking babyboomers here...you have a crystal ball as to THIS generations mortality? I don't either, but I do read the papers, including the death notice section(to see if I'm there)....it's amazing to see the percentage of them in their late 40's, 50's and early 60's.
The "I want everything, and I want it now!" generation, combined with the garbage they call "food" that they consumed for nourishment (for decades), will definitely take it's toll(it's already begun to).
Modern medicine vs. modern day lifestyle choices ....it's basically a push.
