am a caregiver. My wife Joyce and I have tried to share with others here on the net all we could to (hopefully) help medically or spiritually other PD'ers and/or caregivers. Just your being here on behalf of your dad made us know that we are all one big family and we are really not alone. Ive learned there are more smart people and more compassion here than any other place. good luck to you and dad. Chuck T
