In the past three weeks, I have suffered a dramatic andsignificant decline in my mobility, for reasons that my doctors have not yetfigured out.  My ability to get aroundwith a three wheeled roller is almost nil, I have fallen four or five times at homealthough fortunately have not hurt myself seriously, and even getting to andfrom my car is almost impossible for me. However, I have just discovered thatmy retirement community has just purchased a bus that is wheelchair accessible.Today, when I went to see my doctor, I got on my three wheeled electricscooter, which I use everywhere in my home, went down via elevator and out tomeet the bus, got on the bus, got off the bus, made my way to my doctor’soffice, saw him, came back home, and never once had to get off my scooter untilI was safe at home. That may not seem like much to you youngsters in your 60sand 70s but believe me, to a 90-year-old with Parkinson’s disease it ismiraculous
