Everyone knows that feeling. It's interesting how our brains can perceive the same amount of time in completely different ways.

I love it when I'm high, and I become intensely involved in some activity like playing the guitar, eating, reading, playing chess for what seems like hours and hours. Then, I'll check the clock, and it's been about 3 minutes. It's seriously a way to slow down time, because we're slowing down our own reality. And the only reality that exists is the one you create.
