Mark Wellman began climbing mountains when he was 17 years old. He loved outdoor activities, and climbed most of mountains. Then in 1982, while going up a difficult mountain in North America, Mark fell 100 feet. He doesn’t remember much about the accident, except that it was cold and he couldn’t feel his leg.

As a result, Mark can no longer walk. To this day, however, he is still a mountain climber. He takes part in all the same activities he did before, and more besides. Nothing could stop him, not even losing his legs. Since the accident, he has climbed more than fifty high mountains around the world.

In addition to climbing, Mark has been on the United States disabled ski team. He has taken part in two Paralympics Games (残运会). He has made films about physically challenged (有挑战的) people enjoying outdoor sports, he has also written his own story in a book called Climbing Back. The book has given hope and courage (勇气) to thousands of people who are unable to walk.

Nowadays, Mark Wellman lives in California, where he runs a business called No Limits. He often travels around America and gives speeches about his experiences as a physically challenged person. He talks to all kinds of people. Mark tells his listeners that they can overcome any problem to realize their dreams.
