Ever watched a ghost and a human play tag together? It's weird.. the ghost floats around all slow like, the human 'chasing them' runs ahead to where they're about to be, the ghost stops, and stands, out of breath, because apparently ghosts get out of breath from floating around slowly despite being dead and can be tagged despite being intangible.. Ha, I didn't know this until today.
Today I learned that in University, it doesn't matter what you do during your Tuesday and Thursday lecture or class activity. Read a book, play on the computer, learn other skills, eat breakfast, talk on the phone- it doesn't matter. As long as you are there in the right area (and don't pick "sleep through lecture"), your academic performance goes up.
