It’s easy to assume that a given set of habits correlate with survival, and even easier to write a book effectively engaging in survivorship bias. It’s a lot harder to get lucky many times in a row, to have the opportunity to not die. So read the book, keep your back to a wall and an eye on exists, but recognize that none of that would have helped this guy. The two big tings that seemed to have saved this guy is temperament (look at his job for indication she that job followed temperament and and not the other way around) which allowed him to remain calm, and sheer dumb luck.
It is a correct assumption.
I survived this attack ... by not going to Afghanistan.
