Thirty-one-year-old Spencer West recently climbed Mt. Kilimanjaro. That's an accomplishment for anyone, but when you see Spencer West, you wonder how it could have been possible. This climber has no legs.

"My family and I were told by the doctors that I would never sit up by myself, that I would never walk by myself, and that I probably wouldn't be a functioning member of society," he said.

But that didn't break his spirit nor his stride.

A few years ago, Spencer joined a charity called Free the Children helping American kids to build schools in Africa. He climbed Mt. Kilimanjaro with two friends to raise money for the charity and to inspire others who are having tough times.
