Perhaps, but seems unlikely to be suspected as PD. My own first symptom, about 10 yr before diagnosis as I recall, was gradual but relentless loss of physical endurance, that was evident in my frequent mountain backpacking and climbing trips. I tried the RCAF workouts, bought a jumprope, etc., but nothing helped. Cheers, Joe -- J. R. Bruman (818) 789-3694 3527 Cody Road Sherman Oaks, CA 91403-5013
