After 12 years of unwedded bliss, two friends of mine recently got married. The reason: Her job offers health insurance benefits to married couples but not unhitched cohabiting ones. Now it turns out these two may have been at the leading edge of a trend. According to a new poll, 7 percent of respondents said they or someone they lived with decided to get married in the last year in order either to have access to health insurance benefits or to give their new spouse access.
