ROMANTIC LOVE

People sometimes love at the first moment. Among men and women, scientists                       have found that there is a chemical in the brain. 

Relationships do not last forever. When a person first falls in love, NGF levels come from the rush of adrenalin and love of life.

 Dr. Enzo Emanuele demonstrated for the first time that levels of NGF are elevated by analyzing 58 volunteers who had recently fallen in love. 

They also said NGF caused sweaty palms and butterflies in stomachs.
