I'm disabled due to polio. Had it when I was 9 mos old. Screwed up my right side & messed up my left hand/thumb. After 4 surgeries on my legs was able to do almost anything but run. About 15 years ago post polio syndrome hit & now in wheelchair. Muscles getting slowly weaker so I'm doing all I can while I can. The left hand makes it hard to use all the buttons as quickly as I'd like to but I do it. Great job guardian!!! Don't let anything stop you.
