The national survey of married Americans found that 40 percent of those who'd been married at least 10 years said they remained "very intensely" in love with their partner. The study sought to determine whether long-term romantic love was just a rare phenomenon, but researchers found just the opposite. Even for the longest marriages -- three decades or more -- 40 percent of women and 35 percent of men said they were still madly in love.
