Terry Fox 18 when he lost his right leg. Doctors discovered cancer, so it was amputated
. However, Terry didn't feel too depressed about it. Rather, he overcame his disability by running across Canada to money for cancer research. Unfortunately, after 5,373 kilometers and 143 days, his cancer re-emerged and he had to back to the hospital. He died when he was only 22, but his incredible "Marathon of Hope" inspired a worldwide fundraising campaign that has raised 270 million for cancer research.
