If I could, I'll speak very quickly to the medication problem. I agree that it is a major problem. We identified it as one of our risk factors. We notified family doctors that their patients were on eight medications and asked if they could please review them. In many cases, the doctors reviewed them, and the patients were still on eight medications.
In Dr. Campbell's work in Australia, he did a clinical trial in which he actually reduced psychotropic medication--tranquilizers and barbiturates. He had a huge reduction over one year, and that was a successful trial. Unfortunately, at the end of one year, they were right back where they started. It's a really tough thing.
