A new report published in the British Medical Journal has suggested that married life provides a number of health benefits

The researchers went on to add that the benefits of marriage increased over time but only if the relationship was a loving and supporting one. One of the major reasons for an improved life was because happily married couple often ate healthy food while they also took better care of each other.
In contrast having many sexual partners or constant divorces are detrimental to the health which could also shorten the lifespan. Stating that commitment is the most important duty for a man the researchers wrote “Commitment seems to provide networks of supportive and helpful relationships, beginning with the spouse or partner, leading to more healthy lifestyles and better emotional and physical health.”
