Researchers in Britain have carried out the study and found that a large number of middle-aged women spend most time on social networking sites, like Facebook, Twitter, and suffer from chronic back pain due to hours hunched over computers.

The findings are, in fact, based on a poll of 1,000 women, aged between 35 and 50, in Britain.The study revealed three in four women -- 78 per cent -- are in agony because they spend too long sitting at a desk at work or on the net. Of those nearly one in five -- 18 per cent -- endures backache every day.

A third admitted they were in pain every few days and nearly a quarter between once a week and once a month. And almost half -- 44 per cent -- could not walk easily. A smaller number -- 15 per cent -- could not go out socially or work.

"Back pain can be intense and make life difficult for sufferers, with discomfort badly affecting their home, work and social lives," the 'Daily Express' quoted physiotherapist Sammy Margo as saying.
