Who needs sleep?

I usually sleep, at most, about five hours on a worknight. Even when I was working a very physically demanding job, I rarely got more than six hours of sleep. On a weekend I might allow myself eight hours if I get to bed early, but I usually wake up feeling like I'm wasting time sleeping, time that could have - well, could have been wasted on something else.

How much sleep do people typically get? I hear eight hours as a recommended minimum all the time, but I can't imagine finding the time to get that much sleep on a regular basis.

Oh, well, time for bed. If I'm asleep in five minutes and the cats let me sleep through the night, I could get up to four and a half hours before my alarm goes off.
