Sure, stars often appear superhuman on TV—but that doesn't mean they're not susceptible to the health concerns of lesser mortals. In his latest Ask Dr. Oz Hollywood edition (check local listings), the all-knowing Dr. Mehmet Oz fields mind-and-body questions from a variety of bold-face names, including Lost's Michael Emerson, who wants to know what causes black eyes, Valerie Harper, who's seeking exercises for her knees, and Molly Ringwald, who is on the hunt for healthy Greek food.
"It's important to show the human side of celebrities. We are more fascinated with fame than any time I can remember," says Dr. Oz. At least society's obsession does have one upside: "Some people are so intrigued by celebrities, they follow their every move," he says. "I see it as a teachable moment."
And given his own celebrity, Dr. Oz has plenty of those. He's often stopped for advice in the most unconventional of places. "It's hard when I am running to catch a plane in the airport and someone is shouting their medication regimen across the terminal, asking me about side effects," he says. "But I profoundly love talking to people. It's one of the reasons I became a doctor."
