Stress can be deadly, even to the strongest individuals. That's why they're learning to talk about it.
"I'm good to go" is a phrase that Marines and first responders like Mike Washington are usually all too familiar with.
It's often the knee-jerk response to the call of duty, even if emotionally they're anything but "good."
"As firefighters, as law enforcement, as military, we try to play that tough image," explains Washington, a firefighter for the Seattle Fire Department. "And we wouldn’t share if we’re having a hard time dealing with something. We internalize it."
