> how does the average person find 5 hours a day to watch tv?
Watching TV is passive, which means you can do it while doing other things. I watch it while cooking, cleaning the house, doing the dishes, and other similar manual and low-cognition activities. In fact, I can't just sit and watch TV for very long.
But here's what I'm starting to do now -- I set an alarm to make sure I remember to leave the office at 4:30 pm, instead of squeezing in that extra bit of work (or slacking off). That gets me a bit of a jump on the evening, instead of leaving work at 6:30 or so. Seems to be helping a bit.
