Thanks. This may be a good time to point out that life's normal demands have been keeping me busy so l had done only a cursory glance before attempting to piggyback on others' efforts.
In addition to my brother with Parkinson's accompanied by Lewy Body ( dementia) I have a sister who is experiencing arthritis who is curious about hydro generators.
I'm the youngest of four and family genetics have a pretty strong history of longevity.
