I have noticed I've become very Vulcan like during stress. When crisis happens, I seem to be a calm one because I know that getting emotional won't help the situation. I had forgotten that Spock said a similar thing on an episode of Trek until I watched it again a couple of days ago.

Live long and prosper....

Hmm i'm more like a klingon...

I'm more like a human.....

I guess I become a Vulcan Klingon hybrid. I get very logical and analytical about the situation I am in, but then I lash out at people who suggest ridiculous things at that point.
