... may be concerns about his health. He mentioned that after going on an angry tirade, he had a physical reaction to it. He got some sort of discomforting feeling that hung with him. My guess is since he's so passionate about certain things, his blood pressure might have gone up while talking (and sometimes yelling) about the weakness of the American male in todays society, the terrible problem of illegal immigration, and more. He mentioned how he didn't want to drop dead (in the studio). When he had his producers play back the segment, it wasn't any more intense then other similar episodes on his show. It shall be interesting to hear how he proceeds in the future.
