"Some people in the face of extreme pressures, their hormone level is very unique," Aikins at the AAAS annual meeting, said, "This (cortisol) levels peak like everyone else. So When some people sitting in a chair (nervous) want to scream, some people still do not feel under pressure at. "

Born hero

Aikins that cortisol and the combined effects of neuropeptide Y, some people are "wired" hero.

He said that the world is not completely "fearless" man, the hero is not entirely feel fear, but fear they will not show and have the ability to calmly deal with the problem. In view of cortisol and neuropeptide Y secretion differences, this ability can be described as "natural."
