Showing creates mental pictures, it is interactive and participatory because it forces the reader to deduce the facts for himself. Most importantly, most of the physical description does double-duty by explaining another aspect of the hero’s personality or background.
Since the details are tucked in with the rest of the story, the reader as no reason to skip ahead to the good stuff.

This is the primal emotional response, but does not individualize the emotion of the character. The mind shapes the emotion. Present the thought before the physical response. Remember:
stimulus -> internalization -> response
Oh god. I'm going to die. My heart is pounding in my throat. My hands start to shake.
