What kind of problems do teenagers have nowadays?
Young people can meet difficulties everywhere: at home, at school, in the street. They face to different problems. They are  as school problems, emotional problems, health problems, at home with parents ,     misunderstanding  ,  smoking  ,    using drugs   ,   using alcohol drinks  ,    relationships with lovers.  The teenager is kind enough. Someone  tries to get  good education  nowadays.
Someone is sure that the most important thing in life is health, freedom and the ability to adapt.
Someone  go in for different kinds of sport.  Someone enjoy drugs, alcohol, and smoking. Someone try to make the around world better.

As a kind of protest against the values and lifestyles of the older people informal groups appeared. For example  such as Hippies, Rockers, Bikers, Skinheads, Punks, Goths
I believe  a great future is reserved for Modern Youth in Russia
