They're single 36-year-old twin brothers who are not only identical but are doctors and volunteers who gave their time and talents to help survivors of the war in Afghanistan. Gayle talks to doctors Vince and Vance Moss about their careers, dating and the four-month mission in Afghanistan that changed their lives.

In 2005, as stateside army reservists, Vince and Vance say they used their skills as surgeons to operate on soldiers returning home from war. Soon, Vince and Vance say they learned that many of the victims of the war were Afghani civilians who were in need of simple surgeries but were without resources. The brothers say they wanted to help the civilians, so they went on their own—without the protection of U.S. troops—to help Afghanis in need of medical treatment. "We had the support of the military and state department to do this, but basically it wasn't official," Vince says.

As tall, African-American identical twin brothers, Vince and Vance say they stood out in Afghanistan and were fearful that they would be the target of terrorist attacks. "It was after the first surgery, when we came out of that surgical room, and having literally 30 or 40 families with their kids asking us to help them—that is what kept us driving," Vance says. After gaining the trust of the local people, Vince and Vance say they were able to stay in Afghanistan for four months, often performing surgeries by flashlight with few supplies.

Since returning home, the twins, who are also business partners, say they are looking at life differently. With their days of medical school and the army reserves behind them, the brothers say they are single and looking for love—but there is a catch. The girls they date can't complain about how much time the brothers spend together!
