He was seriously overweight. Especially with diabetes you got to lose the weight, and keep it off. Some have even reversed their diabetes thru slimming down and eating healthy.
Man, I was watching his special on Comedy Central last night, and seen that afterwards was a pic of him in remembrance. I was like "WHAT?! When did that happen?" I still haven't really heard anything about it. Gonna miss him. Dude was funny. Loved him on "Tough Crowd" years ago.
