Gabriela and Erika,

Your writing collaboration was clear and full of information. This is a new version with some changes. Please look carefully and see the differences:


Italian scientists said that romantic love lasts only one year. They discovered that Nerve Growth Factor (NGF) increases when a person first falls in love. When a relationship becomes more secure, the chemical fades. They took 58 volunteers who had recently fallen in love. They compared  the levels of NGF when the people were single or in steady relationships and had fallen in love. They found increased levels of NGF in the new romantics. This causes sweaty palms and butterflies in stomachs, and perhaps made young men buy red roses and candlelit dinners.
