Not everyone learned to ride a bike, I am one of those, never could. Have tried static bikes but the angle and weight on wrists gives me trouble. I don't think it is a matter neccessarily of not wanting to do it. As PD progresses things are not so clear cut. Apathy for some, fear of falls, and I did read about speed being disorientating with bradyphrenia. Some get completely normal movement when medicated, others do not get the full range. Its a complex disorder. Those of us who can't look on those of you who can with awe.

My biggest wish is to climb Adam's Peak in Sri Lanka and watch dawn come up from the top. It is not likely though. On the other hand I will happily dance....

Keep on inspiring people, I know you do.........
