I never enjoyed exercise when I was younger and had a difficult time in gym classes, but I have always loved walking. I would on occasion walk across my small city, Flint from center, which is downtown to the north end where I lived. I walked in the Orlando area and Kissimmee many time. I am now 68 yrs and almost 4 mos old and in a wheelchair permanently so I can't walk at all. I sometimes do wheelchair exercise, but can only use my upper limbs and they wear out fast. I have Polymyositis, a muscle disease which is causin gmy muscles to deteriorate. I would love to live another 30 or more years and will do whatever I need to do to extend my quality of life.
