Thank you for this. I will suggest this to a family member. He is very private but his children are LDS and I am sure they would like to see him do this for several reasons. Apparently, my history won't help with this. His sister, my mother has already passed away from it and so has his brother. As an encouragement to others, one lived into his 80's and the one still living is extremely athletic and active for any age much less his. He currently loves kayaking and he is also 80. Both of the two who passed away already had essential tremors from their twenties and on. In spite of the tremors, the uncle who already passed away worked with intricate details and fine motor skills on many movies and was highly regarded in that industry. They were diagnosed with this many, many years prior to the diagnosis of Parkinsons. My mother's mother had the tremors. She was born a surname Day. It is possible that my grandfather Farnsworth also had this (not related to Day). Hope for the cure! Thanks again.
