Retired U.S. Air Force Col. David Roeder spent more than a year as one of 52 American hostages held by Iranian revolutionaries who took over the U.S. Embassy in Tehran in 1979.
"I spent 14 months of my life and getting beaten around and tortured and threats against my family and all those sorts of things," he says.
For many, he adds, the ordeal never ended.
"Quite frankly, I was one of the lucky ones," he says. "I think I'm ok. But there's an awful lot ... who are really hurting. Everything from post traumatic disorder-type depression, to age, of course."
