Who -- and What -- a Survivor Is

Quotable quotes:

"I define a survivor as one who has touched, witnessed, encountered or been immersed in death in a literal or symbolic way and has himself remained alive." -- Robert Jay Lifton.

LIfton, an American psychiatrist and pioneer in PTSD studies from the 1970s, is also the author of "Home from the War: Learning from Vietnam Veterans."
