Telegraph: Researchers in the US charted the ups and downs of more than 2,000 married people over a 20-year period and found a strong correlation between being happily married and in good health.
The team, made up of academics based in Utah and Nebraska, used information gathered during what was the longest study of its kind ever conducted into marital strife, from 1980 to 2000.
Participants were regularly questioned in detail about the state of their relationship and how they felt their spouse treated them.
