Orlando Serrell did not possess any special skills until he was struck by a baseball on the left side of his head on January 15, 1979 when he was ten years old. Serrell fell to the ground, but eventually got up and continued playing baseball. He did not get any medical treatment because he did not tell his parents; for a long while, he suffered from a headache. Eventually, the headache ended. Now 42, he can instantly recall the day of the week, weather and what he was doing for every date since the accident without consicous effort.
