Or perhaps you've put off writing that book you always felt you had in you. You will then have time to write volumes.

The range of things you can do with those extra years is bound only by your desires.
It will be your happy choice to make.

Of course, there will be a statistical few that may not get the full allotment of these extra years. Perhaps a genetic predisposition to this or that disease will make itself felt in spite of the program. If so, you will in any case have made it much farther than you would have otherwise.

And there is the possibility that, having made it that much farther along, the genetic predisposition may at that point in time be amenable to correction. But we are getting ahead of ourselves here - more on that point shortly.

Most of you, at any rate, will get those extra decades, and they will be yours in a well functioning body.

What you do with them will be limited only by your dreams.
