Why having an extra wife may lead to a longer life
The key to a long life could be as simple as getting a second wife.
Research suggests that men from polygamist cultures live 12 per cent longer than those who limit their affections to one woman at a time.
They may also better care of themselves into old age when they have a large family to feed, this week's New Scientist reports.
Sheffield University researchers uncovered the 'benefits' of polygamy by scrutinising World Health Organisation data on marriage practices and on life span.
The analysis shows that men who live in countries where it is common to have more than one wife tend to outlive their monogamous counterparts.
The finding took into account a country's economic situation to minimise the effect of better nutrition and healthcare in monogamous Western nations.
It is thought that the pressure of having to provide for a big families may lead to men taking better care of their bodies and their health. They may also benefit from the care and attention of several wives.http://www.dailymail.co.uk/sciencetech/article-1047659/Why-having-extra-wife-lead-longer-life.html
