Former President Ronald Reagan turned 89 on Sunday, spending the day quietly at his Pacific Palisades home with his family, while at the Reagan Library (in California's Simi Valley), about 700 people gathered to celebrate with a vintage car show, barbecue lunch and country music. Former First Lady Nancy Reagan said Friday on CNN's "Larry King Live" that her husband -- diagnosed with Alzheimer's disease in 1994 -- was "doing as well as can be expected." When King asked about reports from a doctor who said that the former President was deteriorating, she responded, "I don't know what doctor you're talking about." Putting as good a face on the situation as she could, Mrs. Reagan said, "I think, you know, we should talk about more cheery things -- about the wonderful times and the years in the White House, and what we did. And they were great years."
