Dr. Frank Artress, the former Modesto cardiac anesthesiologist turned African bush doctor, has found little time to eat since his story went around the world a month ago. Artress nearly died from high-altitude pulmonary edema while on a 2002 trek up Mount Kilimanjaro, prompting him and his wife, Susan Gustafson, to make a 180-degree life change. They sold everything they owned and moved from Modesto to Tanzania to administer health care in one of the poorest nations in the world. They wanted to give back to the people who ran Artress down the mountain on a stretcher while singing Swahili prayer songs. Every year since, the couple have spent one month in the United States, fundraising at house parties and collecting checks from friends and family. The donations helped them open a small clinic last month in Karatu, where they have already treated patients with broken bones and chronic seizures. In recent weeks, interest in their work has multiplied as Artress' story, about the social power of the individual, has spread on the Internet. The outpouring comes as philanthropy is becoming more personal, through microloans or community service projects in public schools. With technology exposing the plight of the world's poor, volunteerism is on the rise and the Bay Area tops the list of the most-generous regions. Two decades ago, bookstores were filled with best-sellers about how to make a million. Today, books such as Three Cups of Tea and Mountains Beyond Mountains are best-sellers that inspire humanitarian activism and are helping raise millions of dollars for charity.
