Dr. Luanna Marquez is an associate professor at Harvard Medical School and author of Bold Move, a book about transforming anxiety into power. She grew up in Brazil with a single mother who suffered from asthma attacks as a child. Her parents' domestic violence incidents led her to believe she was having panic attacks - but it took 20 years for her mom to put two and two together. "I think all of us can do it, the right set of skills," says Dr. Marquez.
