Wheelchairs and the Joys of having one

I live in a wheelchair and am grateful they were invented. I understand the first one known about was for King Phillip of Spain in 1595, They kept improving them through the years. I am on my second wheelchair as the screws kept falling out of the arm of my first chair, I don't think Tiny Tim had one as they probably were too expensive so he used a crutch. I get around the house well but it does limit my car rides to places of excitement like church as I also do not stand very well to move into a car, There is an expensive cab sevice which takes me to the doctor's office but is too expensive for regular entertainment. I am just happy they were invented,
