2) Department of Defense studies at Yale show heroism might not always be a choice. Some people might be wired for it.
“It may be that some people have stress hormones that run cooler in dangerous situations.” But after studying hundreds of veterans who served in Afghanistan and Iraq, Aikins believes that most tried to run but couldn’t. “Random luck and surviving,” he says, defines many who survive to be called heroes.
