I am male, 48 with PD diagnosed 13 years ago, live in Connecticut, and have just started at Yale Movement Disorder clinic- Dr. Marek. Have just left my career job and am on disability ins. My E-Mail is "[log in to unmask]" . Would welcome mail etc. Question: In the search for common demographics, there is always talk of Well Water vs. City Water, has any data ever been gathered on the kind of pipes? I grew up with city water, but our old house had IRON pipes.... given all the talk of iron and oxidation, just a thought! regards & happy new year, Steve
