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.

(1). Research leader Dr. Enzo Emanuele reported: "We have demonstrated for the first time that levels of

NGF are elevated among people in love, suggesting an important role for this molecule in the social

chemistry of human beings." (2). His team analyzed 58 volunteers who had recently fallen in love. The

researchers compared NGF levels in this group with

those in people who were single or in steady

relationships. (3). They also said NGF

caused

sweaty hands and butterflies in stomachs, and perhaps made

young men buy red roses and candlelit dinners. (4).
