Lots of us touched by those diseases. They're horrible. I have heard it said that Altzheimer's and dementia are kind of like losing your loved one twice; once when the disease takes over, and again when they finally die. Hard business. And I would think that Lou Gehrig's disease is a similar experience, but the brutality of that one is that the person doesn't lose their mental abilities right? Just the rest of the body shuts down? Terrible on a whole other level again.
Sorry for your experiences and loses guys.
