"I fail to see how "eating poorly" and "being fat" has anything to do with "dry eyes" or "restless leg syndrome" though. There are several "new" disorders that most of us call "getting old" that big pharma has taken advantage of. I believe that's the sort of thing Docspud was referring to."

It may everything in the world to do with it or nothing at all. Most people will never know becasue taking the route of rebuilding your diet losing weight and getting exercise is the last thing they will try instead of the first thing. Getting old is 90% mental , people give up or are content to stay where they are in life, toss out the anchor so to speak. all the healthy old people I know are young at heart and willing to try new things.
