I've been in the same office for over a year and the lights have never needed to be replaced. They don't even flicker. This leads me to believe fluorescent lighting probably gets its power from sucking our souls dry. I have evidence to support my theory.

1. Fluorescent lighting seems to last forever.

2. At the end of the day I feel drained although my job requires no exhaustive labor on my part.

Update: I was just told my theory is in Joe Versus The Volcano. I've never seen it. So there.
