美满的婚姻使人长寿，这个已经不新鲜了，它甚至能够延长心脏手术后的存活率~@~

(Health.com) -- Marriage is thought to have a number of health benefits, including greater longevity, less stress, and a lower risk of heart disease, diabetes, and depression.

Now, a new study suggests you can add a better survival rate after heart surgery to the list of health perks. Overall, people who were married when they had coronary artery bypass surgery were 2.5 times more likely to be alive 15 years later than unmarried people, and the happily married fared better than those in unhappy marriages.
