A
Randy Kraus was paralyzed (瘫痪的)．His left side was useless.He'd been a police officer before, and he was strong and able.Now, he felt he could do nothing.
His trouble started with Parkinson's disease, but it didn't end there.In July, 2002, the 60yearold Kraus went into the hospital for an operation on his brain to control the shaking.But during the operation，he had a stroke.He was paralyzed.The doctor said，“You may never walk again and you might not even be able to talk.”
Kraus found that he couldn't lift a fork or take a drink by himself.Physical treatment was so painful and slow.What did he have to live for? So Kraus held the gun against his head.Feeling the cold metal on his skin, he began to consider the pain he would cause for his wife, daughters and grandchildren.He didn't pull the trigger (扳机)．
Andrew Garud, his exercise physiologist (生理学家)，told him，“You are where you are.The pace would be slow；the pain would be real.But as long as you are alive，you will have the ability to get better.”
After three months of working with Garud, Kraus wanted to see if he could stand.He could.Then he took three steps, sat down and cried like a baby.
One step，as they say，led to another.Next he managed a short walk along the edge of a boxing ring (拳击台) in the health club.It was the hardest fight of Kraus's life.People at the gym cheered him on.Garud kept saying he could do more.Now，Kraus can brush his teeth，shave himself and get around the house with a walker.Only the paralyzed can fully understand little triumphs.
