Lady Macbeth praised the healing properties of "sleep that knits up the raveled sleeve of care." Picture a sweater whose cuff has frayed, and imagine that cuff re-knitting itself and becoming whole again. That's what happens to your psyche when you sleep; it restores itself. This bit of wisdom got a friendlier exponent in the form of Jeeves, P.G. Wodehouse's valet hero, who liked to quote it to his feckless young employer, Bertie Wooster, when he came home tired and fuddled from too much reveling at The Ritz. But even if your cares are heavier than Bertie's, rest will lighten them.
