Okay, I don't know if any of you have ever lost consciousness before, so let me just say here real quickly: Don't do it. Really. If you can avoid situations in which you might lose consciousness, please do so. Whatever you do, do not pass out. Trust me. It is not fun. It is not fun at all. Unless, of course, you're guaranteed to wake up having mouth-to-mouth performed on you by a totally hot California lifeguard. Then I say go for it.
