When I was little I figured time was best measured in 30 minute increments. If you had 30 minutes of time on your hands you had enough time to have fun or get something done.

The measurements were based on television time slots. The Simpson’s was my show of choice and a 30 minutes well spent. Often when calculating the negative impact of doing things things that I didn’t want to do, like a doctor appointment, I would figure how many simpsons episodes I would be missing.
