To begin with I'm a member of "the three score and ten" club.  See www.lettertoayoungwoman.com  I have been a pilgrim and a seeker

and have have written a short story that captures the sense o how

we might end up transforming our selves and the planet.

the story is called The Last One and is can be found on many websites
