It's often been said in the 10 years since the terrorist attacks of 9/11 that the world as we knew it had changed forever. But let's face it, the world changed far more for some than for others.
Gary Mathieson is one of those whose life was dramatically altered by the events of that horrible day.
Mathieson, a teacher in Newport-Mesa since 2004, is an Air Force reservist. His military service has taken him away from his family for months, sometimes years, at a time. It's been a strain on his finances and his teaching career, and a burden for his wife, who is also a Newport-Mesa teacher, and his daughter, who just turned 13.
But when the towers fell in New York, Mathieson understood immediately what it meant. At the time, he was teaching in Huntington Beach, and his eight-year stint in the Navy Reserve was due to end that December.
