Dr. Bob Arnot and Mark McEwen in conversation about McEwen's near-fatal stroke. After 15 years with CBS, McEwen shifted his TV career to a metro market. Less than 24 hours after being misdiagnosed with flu symptoms, he suffered a catastrophic stroke. Following a harrowing recovery, he's now back on TV and the author of a memoir about his experience. Dr. Bob Arnot is known to millions of viewers as the former chief medical editor for NBC and is now the host of "Dr. Danger." In a collaborative presentation, Arnot and McEwen will discuss stroke signs and symptoms, prevention and treatment. Event is free. Pre-registration required at 1-888-724-2DOC. Location: Addison Penzak Jewish Community Center, 14855 Oka Rd., Los Gatos.
