I swear I'm allergic to my adrenaline. A few years ago,
  lightning struck nearby our house at the end of dry season right
  before first rain of the season. The rain was heavy but the fire
  was more fierce. Me and a few others here rushed to action,
  wetting down the house, controlling the flames, running back and
  forth getting water (because it was too far for all the hoses so
  the hoses just focused on the house) back and forth back and
  forth. Full speed. After 45 minutes it was finished. Still
  raining, but the fire was out and no longer smoking. My brother
  and sister ran off to help a neighbor who had lightning strikes
  by their house. [the fire department *did* come but they were
  occupied with OTHER strikes before getting to us] My legs were
  scratched up badly from running through "sticky weeds" (they
  have little balls at the end of it that scratch - it's actually
  where the idea for velcro came from) - but by the time I felt
  the pain... I was done. Just done. Knees weren't wobbly. I had
  nothing. Couldn't talk or speak. Felt horrible. inside and out
  and wanted to run out of my skin but couldn't move an inch. Of
  course this is extreme. But even in regular stress situations, I
  can take VERY little and then I have to go to a dark room for
  15-20 mins. Probably slightly autistic spectrum or whatever.
  Anyway, I hate when the stuff takes over. Useful? Sometimes. But
  Rarely.
