Less sex = more happiness?

Is there a link between this article in The Independent:

"People living in the South-east might generally be more affluent. But they are also more stressed and miserable than people in any other parts of the UK, a survey by YouGov has found.
By contrast, those in the South-west, including Devon and Cornwall, are the happiest.
Only 28 per cent of people from the South-east, including counties such as Surrey and Kent, considered themselves "very happy" in their lives. And 22 per cent of people living in the region said they were "not very happy" in their work.
Phillip Hodson, a fellow of the British Association for Counselling and Psychotherapy, suggested that life in the South-west was less materialistic than in the rest of the country. Mr Hodson, who bought a house in Cornwall 12 years ago, said: "People are inspired by the scenery, the sea and the light. The air is clean and fresh, crime levels are low and there is an easy-going tolerance to the region."

and this article on The Guardian newsblog of yesterday about the latest survey of Briton's sexual habits:

"According to the survey, more than a third of men and women have sex "rarely" or "not at all", despite nearly all believing regular sex is an essential part of a healthy relationship. The South West is the most sex starved region, with 45% having sex rarely if not at all. Perhaps all that Cornish cream is blocking vital blood supplies."

Or maybe the newspapers should stop filling their pages with stupid surveys...
