A new study of 8,000 young people in the journal ofHealthandSocialBehaviorshows that although love can make grownups live healthily and happily,it is a bad thing for young people.Puppy love   may bring trouble for young people and can cause depression  .The study shows that girls become more depressed than boys,and young girls are the worst of all. The possible reason for the connection between love and higher risk of depression for girls is "loss of self".According to the study,even though boys would say "lose themselves in a romantic   relationship",this "loss of self" is much more likely to cause depression when it happens to girls.Young girls who have romantic relationships usually like hiding their feelings and opinions.They won't tell that to their parents. Dr.Marianm Kaufman,who works on young people problems,says 15% to 20% of young people will have depression during their growing.Trying romance often causes the depression.She advises kids not to jump into romance too early.During growing up,it is important for young people to build strong friendship and a strong sense of self.She also suggests the parents should encourage their kids to keep close to their friends,attend more interesting school activities and spend enough time with family. Parents should watch for their children's eating or mood changes.If they see some,they need to give help.The good news is that the connection between romance and depression seems to become weak with age.Love will always make us feel young,but only maturity   gives us a chance to avoid its bad side effects. What's the main idea of the passage?
Puppy love may bring young people depression. Parents should agree to their children's love. Romance is a twoedged sword for grownups. Romance is good for young people.
