Single after 40 years of age reduces the chance to live up to 60

Single after 40 years of age or losing a partner without remarriage will be at risk of dying early in middle age and reducing the chance of living up to 60 years old.

>>>Single people don't live long

The recommendation came after American scientists tracked 4,802 survey participants, from about 40 years old until they were nearly 60 years old, according to the Daily Mail. During the study period, 238 participants died, including 32 women.

Marriage increases the likelihood of longevity

Researchers found that people who never married before middle age had the highest risk of death.

Experts say that marriage has a positive impact on lifestyle, helping married people have the opportunity to eat more nutritious foods, have more friends and be encouraged and cared for by their partners.

A recent study conducted in 7 European countries showed that married people had better physical and mental health, reducing the risk of premature death by 15%.

Meanwhile, American scientists have found that cardiovascular patients who are cared for by their partners have a three-fold chance of surviving up to 15 years compared to unmarried patients.

In addition, a Swedish study found that marriage reduces the risk of Alzheimer's dementia by middle age.

The new study was published in the Annals of Behavioral Medicine.
