There is a built-in danger in old age which, if we give in to it, makes aging one of the most difficult periods of life, rather than one of the most satisfying - which it should be. Tye danger of old age is that we may start acting old.
Old age tells us that we ourselves have failed often, have never really done anything completely right, have never truly been perfect - anad that is completely all right. We are who we are - and so is everyone else.
