Thanks for your story GerryW.

I'm not a twin, but picked on the fact that you had more stress in your life than your twin. I wonder if stress can trigger PD in a person, not cause it, but trigger it to emerge sooner rather than much later in ones life? Without getting into details, I had the most stressful year of my life just prior to my symptoms starting at age 58. Just a thought. I look forward to replys from other twins.
