Last Thanksgiving, Navy freshman squash player Tighe Mullarkey was a patient at Walter Reed Medical Center in Bethesda, Md., recovering from a life-saving procedure to correct a condition called congenital lobar emphysema. A year later, he looks back on his recovery and returning to the Academy where he's received a second chance to play collegiate squash, earn his degree and ultimately become a Naval officer. Mullarkey has much to be grateful for this Thanksgiving.
