  • Is Concierge Medicine Worth It?

    Daniel Khani was feeling healthy, but he did have a medical problem or, rather, a problem with medicine: he thought he wasn't getting enough of it. The basic physical he got each year was, well, basic. Khani, a wealthy real-estate investor, was accustomed to better treatment in the rest of his life. So in September, he went to the Concierge Medicine clinic in Los Angeles for what he considered the ultimate in medical care: the same kind the president gets.As part of his Presidential Physical, over two days Khani, 66, underwent a battery of fancy-sounding tests not usually included in a standard exam—"dilated direct opthalmoscopy," "fiberoptic nasolaryngoscopy," several ultrasounds, a tuberculosis test—all of them based on the regimen that White House physicians administer annually. "It made me feel good to be getting the same thing the president's getting," says Khani. Doctors sat with him for hours, lavishing him with personal attention, and they sent him for something even the...
  • Following His Green Dream

    Al Gore just won a Nobel Prize for teaching the world to think green, but he's also showing he knows a thing or two about another kind of green: money. Since 2000, according to published reports, the former veep has transformed himself from a public servant with around $1 million in the bank to a sparkling private consultant with a net worth estimated to be north of $100 million. He's a senior adviser to Google, a board member at Apple and now a newly minted general partner at Kleiner Perkins Caufield & Byers, the Silicon Valley venture-capital firm that made billions investing early in Netscape, Amazon and Google.Gore has pledged to hand over his KP "salary" to Alliance for Climate Protection, a nonprofit he chairs. But the gift is more symbolic than material. Gore's salary—his cut of the 2 percent "management fee" that KP partners get on all investments—is typically a sliver of the total compensation that VCs receive. If Gore's profit-sharing deal is anything like the firm's...

"I learned really early to cover up and hide, and I spent the next 20 years wearing big shirts to cover my chest," he recalls.

  • Haunted By HIV’s Origins

    Michael Worobey, an evolutionary biologist at the University of Arizona, is a nice guy—not the sort to seek out international controversy. But last week he found himself deluged with angry e-mails, and the Haitian Embassy and Consulates across the country were fielding hundreds of equally irate phone calls about him. Biology papers don't usually stir up so much fury. But Worobey's latest research, published in the Proceedings of the National Academy of Sciences, tracks the spread of HIV and suggests that the most common Western strain first hitchhiked its way to America around 1969 in the body of a single person—a person who almost certainly contracted the disease in Haiti.Worobey says "Haitians are blameless for the spread of HIV. They were simply hit earlier." But a lot of Haitians feel offended anyway. Many of HIV's early victims in the West were Haitian immigrants, a link that led to "an adverse immigration policy in the United States and feelings of persecution and denial,"...

  • SoCal Under Siege

    Even as flames raced up the dry canyon toward his house in rural Agua Dulce, north of Los Angeles, Bob Baker refused to evacuate. In minutes, the inferno was roaring at his backyard. "It's all over," Baker thought. But then, bucketfuls of water began to fall from the sky as a lumbering air tanker passed overhead and doused the flames. Baker's brush with death last Sunday marked the beginning of a disastrous week in southern California's long history of wildfire. Fueled by dry Santa Ana winds blowing from inland deserts, 16 fires ignited virtually at once in the drought-stricken land, from Malibu to the Mexican border. (Two fires were chalked up to arson.) Flames overwhelmed firefighters, scorched more than 800 square miles, displaced more than a half-million people, destroyed or damaged some 2,000 homes and killed at least 12. Overall, insured losses are expected to top $1.6 billion.When the winds calmed, officials and civilians began asking how to avoid the next inevitable...
  • Fear and Allergies in the Lunchroom

    It's 1 p.m. at Mercer Elementary School in Shaker Heights, Ohio, and Lena Paskewitz's kindergarten class is filled with the happy hum of kids getting ready for their favorite part of the day: lunch. Caleigh Leiken, 6, is toting a pink Hello Kitty bag her mom has packed with goodies: strawberry yogurt, string cheese, some veggies and a cookie. But there's one childhood staple missing—a PB&J. Caleigh was diagnosed with a peanut and tree-nut allergy when she was just 7 months old. Nuts are a no-no at her table in the Mercer lunchroom. Her allergy-free friends can sit there, but only if their lunches have been stored in a special bin and carefully inspected by the teacher. Home, too, is a nut-free zone for Caleigh. When she goes trick-or-treating this week, her candy will be scarier than any costume; she won't be able to eat any of it for fear it's tainted with peanut residue. For Caleigh's mom, Erika Friedman—whose other two kids also have allergies—food can seem like an enemy. "We...

  • Living With Disaster

    Younger might seem irrational. But to psychologists who specialize in the mental trauma associated with natural disasters, his response is normal--perhaps even healthy. "After a disaster, there are people who flee and people who stay and become more proactive," says Gilbert Reyes, author of the 2005 "Handbook of International Disaster Psychology." "Both are ways of coping and both are normal."  The key: people who see their responses to disaster as a sign of personal weakness are more likely to suffer long-term trauma, psychologists say. "That's the single best predictor of how long it will take people to recover," says Gerard Jacobs, director of the University of South Dakota's new Disaster Mental Health Institute.The field of disaster psychology has exploded as an increasing number of people like the Youngers choose to live in catastrophe-prone regions of the country. With each wildfire, hurricane and flood, researchers find more answers to intriguing questions: why do some people...
