Can we sleep less?

This is a great article. I often wish I didn't have to sleep at all. The obvious problem, though, would be boredom. Without sleep, perhaps we would all become like the immortals in Gulliver's Travels--people completely embittered and sick of life. I like to think that Swift's point was that dying wasn't the central problem so much as the imperfections (to put it mildly) of life. Being awake all the time might lead to similar epiphanies.
