     At a young age, Patti Wilson was told that she was an epileptic(癫痫患者). Her father, Jim Wilson,

is a morning jogger. One day she said, "Daddy, I want to run with you every day, But I'm afraid I'll have

a seizure(发作).

     Her father told her, "If you do, I know how to handle it, so let's start running!"

    That's just what they did every day. It was a wonderful experience for them to share. And there were

no seizures at all while she was running. After a few weeks, she told her father, "Daddy, I want to break

the world's long-distance running record for women."

     So she did. That year, she wore a T-shirt that read, "I love epileptics" and completed her run to San

Francisco. Her dad ran every mile at her side, and her mom, a nurse, followed in a car behind them in

case anything went wrong.

     In her second year in college, Patti's classmates got behind her. They built a giant poster that read,

"Run, Patti, Run!"

     Her foot was injured when she was running to Portland. A doctor told her she had to stop her run.

     "Doctor, you don't understand," she said, "This isn't a whim(突发的奇想)of mine. I'm doing it to

break the chains on the brains that limit so many others. Isn't there a way I can keep running?" "Yes, but

it would be incredibly painful." The doctor said. She told the doctor just to do it.

     At last she finished the run to Portland and completed her last mile with the governor of Oregon.
