When I am old (year 2051 will make 60) I am probably on some life-extension plan to keep my youth or whatever left I have of it, if not reversing the effects of aging had on my body.
I want to live as long as I possibly can, since I think the future will be the best times of my life. It's just this time period is transitioning from ancient times to modern age, technology just improve within the last 100 years, it barely touched the possibilities of the future. When technology has been around for thousands of years then I'll say it reaches its peak.
It's an exciting age to live in too.
