I can't believe the parent post is moderated +4, Insightful. That has got to be the most shallow and thoughtless sentiment I have ever encountered. The Alzheimers will make it more difficult for him to manage his diabetes and other illnesses. The increased burden on his family and his own sense of loss of identity (at least during the onset of the Alzheimers) will also makes things worse.
Nothing like a positive comment from someone who simply doesn't care...
