Committed to walking in every way you can imagine

The story of prosthetic I wear is based on necessity. I was told to stop wearing a prosthetic leg because I was going to break the femur bone left on the left side of my body, as my leg was amputated while I rode a motorcycle in 1974. 

By 1996 my use of prosthetic legs was coming to a punishing finish  because my bone infected stump couldn't take the wear and tear of prosthetics. 

I read a story in a daily newspaper's once a week Science Digest, about a study of the human leg in motion.

They said it resembles a pogo stick, so I bought one, put it on, and haven't stopped walking since 1999. 

(Well I actually engineered a prosthetic leg version and tried it on a few people, and they all liked it.)
