Ananova:

Eight out of 10 adults are so addicted to their mobiles they can't turn them off during sex.

The majority of adults questioned said they could not get through a day without their phone.

Social anthropologist Kate Fox said: "They have restored our sense of community and provided a highly effective antidote to the pressures and alienation of modern life."

Most of the 18 to 40 age group said a mobile has improved their lives reports the Mirror.

A quarter of the 16,500 questioned said they would feel isolated if they lost their mobile and nine per cent said would be unable to carry on normally.
