My medical evaluation at age 50 was a sobering experience, especially when I wondered what the next 50 years had in store for me and my body. When I turned 20 the thought of being age 50 seemed like a remote galaxy far, far away. I suddenly turned 50 and realized I have been on this planet for quite some time. I soon was looking at my body as a “vehicle”. I thought: “how many years do I have left with my body”?
