Oh, the 50's were marvelous! If you've been careful you will have generated a bit of financial stability so you don't have to worry as much as you did in your younger days. You can easily take care of yourself and stay in shape. The aging process and the injuries of youth haven't caught up with you yet. People respect you and start saying "sir" or "ma'am" when you don't expect it. You have developed a sense of perspective and gained experience, perhaps even a little wisdom too. And you may have collected a few interesting bikes!
