Yes, Andy, we do sleep about a third of our lives away.

And I agree, it would be nice to have a gauge on us to let us know when we need to get some shut eye or when we've had enough, much like a battery light that comes on to tell us it's time to charge a certain device for optimal use. Green means go. Red mean stop.

Earlier this month when Andy Rooney gave his classic spiel during the last segment of 60 Minutes, he talked about sleep. He doesn't quite understand why so many people have problems with sleep, especially since he "can sleep night or day, sitting, standing, or lying down" and he admits to falling asleep right at his desk or on a bus going across town. He can get along on 7 hours, and thinks that anyone who gets 9 hours or more is sleeping his or her life away.

Andy's quips were no doubt enjoyed by many. But a few big topics Andy failed to cover, though, are sleep's impact on:
• Overall health
• Memory, and
• Ability to get things done (ahem, like work into nineties and have the energy to go on television on a weekly basis).
