I think I was lucky to come of age in a place and time - the American South in the 1960s and '70s - when the machine hadn't completely taken over life. The natural world was still the world and machines - TV telephone cars - were still more or less ancillary and computers were unheard of in everyday life.
I am also hugely excited to then be competing to defend my three Paralympic titles at the Paralympic Games. I believe we will see some amazing times posted and I am very much looking forward to what will be an incredible Olympics and Paralympics in London.
