Aging happy and well, instead of sad and sick, is at least under some personal control. We have considerable control over our weight, our exercise, our education, and our abuse of cigarettes and alcohol. With hard work and/or therapy, our relationships with our spouses and our coping styles can be changed for the better. A successful old age may lie not so much in our stars and genes as in ourselves.
Our lives are like the talents in the parable of the three stewards. It is something that has been given to us for the time being and we have the opportunity and privilege of doing our best with this precious gift.
