Health issue cancels Robin Williams shows

Comic experienced shortness of breath, his Web site says

Comedian Robin Williams has postponed four planned performances in Florida due to health issues, according to his Web site.

Williams was scheduled to perform his one-man show, "Weapons of Self-Destruction,: in Hollywood, Orlando, and Tampa, but experienced shortness of breath. The comic "is currently being evaluated by doctors who are recommending a week of rest," reports RobinWilliams.com.

The Miami Herald, however, reports on its Web site that "sources say (Williams is) currently at a Miami hospital with heart issues and could be laid up for a while."
