Or so says scientists who studied the brain scans of couples who had been together for 20 years versus couples who had recently fallen in love. They found that “one in 10 of the mature couples exhibited the same chemical reactions when shown photographs of their loved ones as people commonly do in the early stages of a relationship.” In other words, that “spark” that couples typically feel at the beginning of dating continues to exist for at least 20 years. These couples were dubbed “swans” by the scientists because the birds mate for life (as do foxes, lobsters, and penguins). [Times Online]
