So, let's say there's a massive earthquake, you're on a plane that's on fire or there are mutated killer sharks taking over your underwater testing facility..how would you react?

Would you be the plucky hero who motivates everyone and gets them the hell out of there?

Would you be the gibbering wreck that cries, says things like "we're all doomed" and needs a good slap every 20 minutes?

or

Would you be the selfish, morally questionable character who threatens the lives of everyone else by looking out for number one?
