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

意大利科学家发现，大脑中催生爱情的化学物质会在一年后消失。恋爱初期的幸福快乐也不会永远持续。来自帕维亚大学的研究人员发现，恋爱初期，化学物质“神经生长因子”逐渐增多。恋爱致肾上腺素上升，“神经生长因子”水平随即增高。一年左右，化学物质消退。

Research leader Dr. Enzo Emanuele reported: “We have demonstrated for the first time thatlevels of NGF are elevated among people in love, suggesting an important role for thismolecule in the social chemistry of human beings.” His team analyzed 58 volunteers who hadrecently fallen in love. The researchers compared NGF levels in this group with those in peoplewho were single or in steady relationships. They found increased levels of NGF in the newromantics. They also said NGF caused sweaty palms and butterflies in stomachs, and perhapsmade young men buy red roses and candlelit dinners.

据研究主任埃马努埃莱报告：“研究学家首次得出结论，“神经生长因子”水平在热恋中升高，在两性发展中，该分子扮演了重要角色。”研究人员对58名热恋男女进行研究。就“神经生长因子”水平，与单身或关系稳定男女进行了比较。发现热恋情侣“神经生长因子”不断上升。并称“神经生长因子”会导致手心出汗，神经紧张，男方购买红玫瑰，举办烛光晚餐更是清理之中。
