FYI for my fiernd Dave in Michigan who asked about my Dad, after much additional testing we have validated the statement made by wine drinkers that a glass of wine a day is good for you! One of my Dad's doctors had advised him to abstain from drinking any alcohol, and I guess that his body chemistry with all the medicines he is taking was thrown for a loop. He resumed his drink a day and is eating better and putting on some weight!
Thanks, Dave, for caring enough to ask!
