Romantic love 'lasts just a year': "Some couples may disagree, but romantic love lasts little more than a year, Italian scientists believe. . .
In those who had just started a relationship, levels of a protein called nerve growth factors, which causes tell-tale signs such as sweaty palms and the butterflies, were significantly higher."
According to those signs, I am in love with my classes and upcoming finals. Good to know the feeling won't last.
