B

I’ve just done my first jump since the accident that nearly killed me just a year ago. As I was lying in hospital, thinking that I would never skydive again, I wasn’t feeling glad to be alive. Instead I was wondering how I could possibly live without it.

It all started one evening after another nine-to-five day. I was sitting at home thinking, “There has to be more to life than this,” when an advertisement came on the television: “Try skydiving!”

The next day, I called the nearest skydiving centre and booked my first jump.

I will never forget my first jump. It was a beautiful, cloudless day and the sun was just going down. As I pushed myself away from the plane at 11,000 feet, my mind went blank.

Words cannot describe the excitement I experienced while I was free-falling. That was the most amazing four minutes of my life.

From the first jump, I was hooked. I started spending every free moment I had skydiving. At work, I sat in front of my computer and imagined ways of making more money so that I could jump more often.

The accident happened on my 1,040th jump. Another skydiver collided (碰撞) with my parachute (降落伞) at 80 feet. I fell and hit the ground at about 30 mph, face down. I broke my legs, my right arm and my nose. I lost 6 litres of blood, 19 teeth and 25 pounds of fat. I was lucky to be alive.

People who have never experienced skydiving will find it hard to understand that my only motivation to get better was that I could do it again. All I can say is that for me, skydiving is life and life is skydiving.
