In the event of a zombie apocalypse or an alien attack, I would most likely be toast. I have a strong survival instinct, that is not a problem, in fact, I think my survival instinct is a little too strong thanks to my neurosis. Instead of gallivanting across fields and shooting zombies in the head when the zeds attack, or coming up with clever ways of infecting aliens with UTIs, I think I would be most inclined to be curled up in a little ball trying not to move or make any sound at all, so as to not attract the attention of anything that might want to eat my brain and/or lay eggs in me to propagate their species. Yes, fortifying and staying put sounds like the best plan for me. And I would need a bathroom nearby at all times.
