The rumor that I had heard from a couple of sources on campus was that Lloyd has Parkinson's and was diagnosed in 2001. I would back this up with some odd speaking habits he has. Watch his video eulogizing Bo at the Stadium. He has a number of nervous hand movements where is constantly moving his hands into and out of his pockets. I had noticed this tick at a couple of events where Lloyd was the speaker. While I'm not a physician, this behavior seemed very odd. When I had heard the Parkinson's rumor, it fit with his behavior. I thought that Angelique Chengelis (spl?) had put out an article shortly after his retirement about this as well. There is also a post on the Wizard of Odds (http://thewizardofodds.blogspot.com/2007_11_01_archive.html) mentioning it.
I believe he has rickets. Just kicked the scurvy.
