I don't have those symptoms, I Googled them and I doubt I have it but I'll mention it to the doctor just in case.
Also, he's not being racist, he's joking about Overeem kicking Brock in the stomach and finished him that way, as Brock had diverticulitis.
He through in the "black" part because of his racist remarks regarding Asain's looking "gross" in the hot woman thread. I just don't dig this man's style. I have my own trollish tendencies at time so I won't hate too much.
