Answer 1

Looks all right from my knowledge of psychology/biology, but it's not a physics question...

Answer 2

"Fright - fight or flight" seems to fit with some of these. To fight or to run needs adrenaline which sort of confirms the first two. and, actually, maybe the fourth, since once the fright has hopefully passed, the person needs to recover from the source of the fright and the adrenaline - a lot more than in every day life - "rush". Presumably extreme sportspeople have a way of doing this, but people in the military probably have it much harder because actual LETHAL fighting is stressful. PTSD is probably very common among soldiers, although dressed up as "shell shock", and possibly "looked down on as weakness". I recently saw a TV show featuring the UK's SAS (Special Air Service) and their training, including the notorious "resistance to interrogation" bit. One of the people on the show was an ex SAS man "Foxy" who had had to be discharged from the army for PTSD. He'd presumably got into a very bad tangle, possibly somewhere in the middle east, and had paid the psychological price for it. Of all the SAS shown in the programme, he came across to me as the most human/gentle (not what's needed in the SAS, i don't think)
