In fact, we ought to be very grateful that we are growing older. If I had the privilege of getting younger instead of getting older, it would be the most horrible thing that could happen in my life. As the years regressed, you would lose each one of your grandchildren and then each one of your children and all the good and happy experiences you have accumulated all these years. I would not give up one year of my life. If we would avoid old age, we must be interested in the life of today.
Nothing is more withering and deadening than loss of interest.
There are those in their 20s who are fed up. They face life without enthusiasm and joy. It is exciting to think about tomorrow. If I were answering that question I could write many things, but I think the one that excites me the most is the thought that someday we will be able to be in communication with beings on some other planet. It may be that there is civilization on another planet far more advanced than our own, and what a glorious thing it would be to be in contact.
