[May you live to be so old that your driving terrifies people.]
I want to live a very long time (billions of years) but not with decreasing abilities that terrify others with the dangers I pose, but rather with increasing abilities in ever expanding domains, and increasing confidence from those around me that I pose very low risk and am very useful to have around.
Such has seemed possible to me for over 40 years (since completing my undergrad studies in biochemistry). Many others are now doing a lot of serious work on indefinite life extension and expansion of human capabilities.
