Tying the knot is unraveling in Japan

It was so simple, once upon a time. The 14th-century "Tsurezuregusa" ("Grasses of Idleness"), random musings of a monk named Yoshida no Kenko (1283-1350), is a perennially delightful source. "A man should never marry," wrote Kenko. "I am charmed when I hear a man say, 'I am still living alone.'" But Kenko also said, "A man may excel at everything else, but if he has no taste for lovemaking, one feels something terribly inadequate about him."
