Romantic love lasts only a year

Italian scientists have found that the chemical in the brain which makes us romantic disappears over a year. They say this explains why the happy, wonderful and confident feelings we experience at the start of a relationship do not last forever. Researchers from the University of Pavia discovered that levels of a chemical called Nerve Growth Factor (NGF) greatly increase when a person first falls in love. NGF levels come from the rush of adrenalin and love of life that occur when new love blossoms. The chemical fades over a year or so after people become more secure in a relationship.
