Too little physical activity has long been recognised as bad for health and recently researchers have focused on the effect of too long spent sitting down.

London - More than a third of women would check their partner’s texts or emails to see if they were cheating, a survey has found.

Some 37 percent agreed that snooping on their other half is acceptable if they suspect “bad behaviour”, compared with 29 percent of men.

As well as reading messages, respondents said it was all right to go through their partner’s contact lists to root out suspicious additions. Facebook accounts were also perceived to be fair game.

The survey of 2,000 people by the American over-50s dating website OurTime found that younger people were more paranoid about their partners, with 36 percent of those in the 18-34 age group prepared to trawl through their significant other’s correspondence. Just 26 percent of over-55s would do so.

The news that women are more likely to peruse their partner’s private messages contrasts with a recent study by insurer esure. It found that one in ten men had hacked their partner’s passwords to check their social network accounts, compared with just six percent of women.

Would-be cyber-snoopers are often able to guess their partner’s passwords, as most of us use names, numbers or phrases that relate to our personal lives. Birthdays, mothers’ maiden names and telephone numbers are all typical choices – yet none of these should be hard for those closest to us to recall.

Relationships expert Jean Hannah Edelstein, the author of Himglish And Femalese: Why Women Don’t Get Why Men Don’t Get Them, said: “If you are looking at your partner’s emails and text messages then there might be wider trust issues in your relationship. It might be time to have a conversation about what you really want from each other.” - Daily Mail
