Not to be morbid, but my current only predictions are on who will die. I won't go to the death polls, so don't suggest it.
Gerald Ford - Liver Failure - He just looks bad.
Chuck Yeager - (He is the man I want to be. I wish he could live forever because he is THE AMERICAN HERO.) Pneumonia (I only say this because he looks too healthy to have heart failure, and I am worried because he has been on TV a lot, but it is all old footage...and this is what they do when someone is in failing health.)
George Carlin - Heart Failure - His drug use will finally catch up to his angry attitude
Don't know about the other two but I agree with you about Gerald Ford, hasn't he been in and out of the hospital a couple of time during 2005?
