Terrific story!
Three guesses as to who I thought of when I read this paragraph (and the first two don't count):
QUOTE
Wain defined heroism as quick response to a changing environment, like a driver who swerves into another lane for the purpose of avoiding an oncoming car and, in the process, saves the life of his passenger. "That wasn't his intent," he said. "But being flexible and shifting is a higher level of intelligence. The people who can't change die."
"Wain" is a psychologist at Walter Reed.
