In the past eight years, more than 35,000 wounded American soldiers have returned home from Iraq and Afghanistan. One such veteran is Michael Jernigan, who was a Marine corporal on duty in Iraq when he was hit by a roadside bomb on August 23, 2004. Since then, he's been featured in the documentary, Alive Day: Home from Iraq and has written for the New York Times' Home Fires blog. He helps other vets get guide dogs through the Paws for Patriots program; and he studies political science. The severely disabled Marine says deepest wounds are the hardest to see.
