Interesting study shows that those who live past 100 years still have the genetic disposition for common afflictions but their genetic disposition for living trumps them.
Also interesting that now we hear about how we are living to age 80-85. What happened to all the malarkey about life expectancy being 72-75? The latter figure does not take account of the rapid pace of technological advances. Neither does the former, fully, for that matter. I maintain that those middle aged and younger are now effectively immortal as the pace of technology will keep them alive, through crude replace and repair, until about 2040-2050 when mind uploading, the digitization of all mental processes, will be achieved.
