““Rescuers tended to be decisive, fast-thinking, risk-taking, independent, adventurous, openhearted, rebellious, and unusually flexible—able to switch plans, abandon habits, or change ingrained routines at a moment's notice. They tended to be nonconformists, and though many rescuers held solemn principles worth dying for, they didn't regard themselves as heroic. Typically, one would say, as Jan did: "I only did my duty—if you can save somebody's life, it's your duty to try." Or: "We did it because it was the right thing to do.””
