I like Barbara's vision of the dog team in northern snow and ice--refreshing!! Here are two non-answers,but I hope they help, and a good word for exercise classes 1. Breathing Difficulties -- a few ideas for Moira to pass on -Is it reaction to heat? The drugs mess up our heat regulating system. -Sometimes the chest muscles are weakened by the parkinson's. -Is it dystonia? -Bromocriptine can cause lung problems- rare but has occurred at very high dosage(an xray will show abnormality). 2. 'Invisible Tremor' --is not all that unusual. I and others at exercise class have it from time to time. Mine is in my right leg and it is very irritating. I had no visible tremor for the first 5 years. 3. Exercise class is a place for informal learning. It is a reason to get out of the house. The workout makes you feel better. Meeting friends lifts your spirits. Our class is not operating this summer--we miss it. Anne
