When Max Montgomery met Andi Traynor for a first date, he had high hopes. They went surfing on a California beach early in the morning and had a great time. Exhausted and happy, the couple left the ocean. Then, out of the blue, 56-year-old Max collapsed. He lay on the sand, silent and still. Fortunately, Andi was a doctor, whose years of training kicked in. She immediately began to perform CPR.
