According to Harvey Mackey, 61 percent of famous people didn’t achieve their most noble achievements until after 60 years of age. So, there is a great deal of advantage to remaining in good health until your later decades of life. In the 19th century, Victor Hugo said ‘‘Forty is the old age of youth, fifty the youth of old age.’’ At the beginning of the 21st century, we can now safely say that 50 or 60 is only the beginning of the second half of life. On December 31, 2004, there were 41 documented ‘‘supercentenarians, individuals over 110 years of age.’’41 By the middle of this century, many longevity researchers believe these numbers will increase dramatically.
We have discussed some of the Bridge One strategies we can use to keep our bodies in good health until the Biotechnology (Bridge Two) and Nanotechnology/ AI (Bridge Three) revolutions find full expression. There is no doubt that the 21st century will be worth living to experience. By following the Bridge One strategies that exist today, many people alive today will have the opportunity to see it in its entirety.
