London, Jan 4 : If you thought true love was something just restricted to movies and soaps, then here's a piece of information: brain scans have revealed that couples can respond with as much passion after 20 years as most people exhibit only in the first flush of love.
Shakespeare once said that "love is an ever-fixed mark / That looks on tempests and is never shaken". Now, it seems, he was telling the truth, at least that's what researchers at Stony Brook University in New York think.
Scanning the brains of people who have been together for 20 years, the scientists found that about one in 10 couples still display elements of "limerence", the psychologists' term for the obsessive behaviour of new lovers.
