It was June 15, and in two days I would be turning thirty. I was not sure about entering a new decade of my life and feared that my best years were now behind me.

My daily routine included going to the gym for a workout( 锻炼) before going to work. Every morning I would see my friend Nicholas at the gym. He was seventy­ nine years old and in terrific shape. As I greeted Nicholas on that particular day, he noticed I wasn't full of my usual vitality(活力)and asked if there was anything wrong. I told him I was feeling anxious about turning thirty. I wondered how I would look back on( 回顾)my life once I reached Nicholas's age, so I asked him, “What was the best time of your life?”

Without hesitation, Nicholas replied, “Well, Joe, this is my philosophical(哲理的)answer to your philosophical question:

When I was a child in Austria and everything was taken care of for me and I was nurtured by my parents, that was the best time of my life.

When I was going to school and learning the things I know today, that was the best time of my life.

When I got my first job and had responsibilities and got paid for my efforts, that was the best time of my life.

When I met my wife and fell in love, that was the best time of my life.

The Second World War came, and my wife and I had to flee Austria to save our lives. When we were together and safe on a ship bound for(开往)North America, that was the best time of my life.

When we came to Canada and started a family, 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, Joe, I am seventy­ nine years old. I have my health, I feel good and I am in love with my wife just as I was when we first met. This is the best time of my life.”
