Flight of Fight Reflex...what happens under stress to the Human Body
 

Check this out, it's not spot on, but one of the closest posters I've seen on it except your pupils constrict if I remember right.

Fear is not bad...it's what keeps you alive and when you stop fearing you die...

Cool poster.:tu:

With fear, the pupils dilate. That way your sense of sight is able to see more. The poster is right on the pupils. Very cool poster!!!!

Thanks for sharing it!
