It is June 15, and in two days I will be turning thirty years old. I am afraid that my best years will be behind me. I usually go to the sports club to exercise before going to work. Every morning I see my friend Nicholas at the sports club. He is seventy-nine years old. I asked him, “What was the best time of your life?” “When I was a child in Australia and was taken care of by my parents, that was the best time of my life. When I was going to school and learning the things, that was the best time of my life. When I got my first job and got paid for my work, that was the best time of my life. When I was a young father, watching my children grow up, that was the best time of my life. And now, Jack, I am seventy-nine years old. I have my health and feel good, this is the best time of my life.”
