Between 65 and 85 years, married men and women had a longer TLE [Total Life Expectancy] and ALE [Active Life Expectancy] than unmarried men and women. For example, at 65 years, TLE for married men was 18.6 years, 2.2 years longer than unmarried men, and ALE for married men was 12.3 years, 2.4 years longer than unmarried men. Similarly, at 65 years, TLE for married women was 21.1 years, 1.5 years longer than unmarried women, and ALE for married women was 13.0 years, 2.0 years longer than unmarried women.

In another thread someone posted that "it's universally agreed that unmarried women have longer life expectancies", so I guess the question is, universally agreed by what, people who deny science?
