Well recently I heard this song called Kissin u, and the lyrics made my day.

"I might die when I forget to breathe"
Um, no, you'll definitely die.
"
When I'm kissing you it all starts making sense
and all the questions I've been asking in my head...
Crystal clear it becomes when I'm kissing you"
That's amazing. I want to bring that guy along for my math exam.
"And the world around me disappears
cuz when I'm kissing you my senses come alive"
Well there's nothing much to sense if the world disappeared, right? Especially since the world includes the magical person you're kissing -.-

Really, I think this guy could become the Oracle. One kiss and all your questions are answered o.o
Oh, maybe he has mutated saliva that stimulates the brain! yes, that's it.
