'A Cathedral of Courage': NYPD Adds 19 Fallen Heroes to Memorial Wall


500 wounded warriors from around the world will compete in this week's Invictus Games, an international Paralympic-style multi-sport event.

Dr. Marc Siegel spoke to former President George W. Bush about the importance of the games, which take place in Orlando, Florida, at Disney's ESPN Wide World of Sports Complex, and the incredible men and women who are competing.

"To meet these athletes is remarkable," Bush said. "These are people who have overcome significant odds, and they did so by being the master of their fate."

Bush said the games are an important reminder of our veterans who are returning home with serious injuries, some that can be seen with the naked eye and some that cannot.

He pointed to PTSD and traumatic brain injury, saying that we must work to remove the stigma that can often be associated with those "invisible" injuries.

"Your job and my job is to help these vets understand it's courageous to say, 'I need some help,'" Bush said.

The former president added that even though he's no longer in office, he's committed to helping veterans.

"I intend to use whatever capabilities I have to get them the help they need."

The Invictus Games, a creation of Great Britain's Prince Harry, will bring together athletes from 15 countries to compete in 14 sports, starting Monday and lasting until Thursday.
