There are some simple BOTECs you can do to convince yourself to the
contrary, however the simplest way is just take a stroll thru the local
cemetery, bring along the envelope upon which you make actual calculations
if you wish.  Go into the older sections.

While travelling on the US east coast, I have personally actually seen
cemeteries with graves put there 50, some more than 60 years ago!  I have
heard that in Europe, Africa and Asia and such countries as that, there are
graves still older than that.  The mind boggles.

Stroll thru, do the math, you will find that *plenty* of old timers lived
past 65, plenty of them did.  Then take 300 million Americans, estimate the
percentage over 65 now, and there is no damn way half the over 65ers are
alive today, not a chance.  I might buy the notion that half of all those to
reach 100 are alive.
