MAYBE:A bigger question might be, how will WW society deal with old people who are supposed to be dead by now. MAYBE TRY LEARNING FROM THEIR EXPERIENCE!
That's get the young whipper-snappers going!
Healthy old people could be a huge benefit to society...working longer, staying off social security, much less spending on medicare.
Also people living longer productively might have other effects...why bother warring when there is a potential loss of 70+ years of good life after age 21?
