2012-12-24 Skiing well in choppy powder and small moguls in spite of Parkinson's disease
It has been over 15 years since I was diagnosed with Parkinson's disease. This video was filmed at Osprey Way at Mt. Bachelor, near the top of the Northwest Express chairlift. Wonderful snow this day but visibility was terrible. We were skiing in clouds, temperature was in the low to mid 20s, and we stopped often to scrape ice off the goggles. It is surprising that so far this ski season, I seem to be am skiing better than last year. My main symptoms (tremors, slowness of movements, and decreased coordination) are worse in my left arm and leg than in my right arm and leg – but so far this year, the left hand is quicker in pole plants and drops down less after each pole plant.
