Cigars suck. Grant, Freud, Limbaugh. etc. etc. etc.
They affect some people differently. Winston Churchill was a cigar smoker, and lived to be 90.
Although I'm sure the cigars didn't help, Limbaugh was also, by his own admission, a chain smoker of cigarettes from his teens through his 30's when he finally gave up smoking cigarettes and switched to cigars. He told a story about it once, he said all the guys trying to get into radio were chain smokers back in the day. He said the reason was that they believed smoking gave you a deeper more gravely voice which was better for radio.

Rush is a great man but his foibles cost him. Most likely lost his hearing due to a pill addiction and now this.
