We're all love addicts

We are all addicted to love, scientists have discovered.

Chemicals released by the brain when we meet the perfect partner are just as addictive as crack cocaine or heroin.

And when our relationships come to an end, the effect is like going cold turkey.

The research was carried out by Dr John Marsden, head of the National Addiction Centre at the Maudsley Hospital in London.

'Wanting more'

He said: "Attraction and lust really is like a drug. It leaves you just wanting more.

" The first flush of love is temporary, he said, and could help explain the seven-year itch.

"The findings also investigate the link between people's smells, facial features and genes.

"Being attracted to someone sparks the same incredible feelings no matter who you are. Love really does know no boundaries," said Dr Marsden.

When we are attracted to someone part of the brain which processes emotions is fired up causing the heart to pound three times faster than normal.

Opposites don't attract

Blood is diverted to the cheeks and sexual organs, causing the feeling of butterflies in the stomach

The research looks at why we are attracted to some people but not to others and what people really look for in an ideal partner.

It suggests that people look for similar features to themselves - rather than opposites - as they are searching for characteristics in their mother and father, who have already been successful raising a child.

Sex booby-trap

Dr Marsden's research also revealed that, "sex is booby-trapped" to make people bond with their partner.

"Your body has evolved over millions of years with one aim - to go forth and multiply, so while having kids may not be on the agenda just yet your body has a few tricks up its sleeve to drag you in that direction," he said.
