Teenagers.


Giving up smoking is a good idea - in fact, it is one of the most important things that someone can do to improve his or her health. I recommended having a No-Smoking-Day. And it took place at the end of April at my school. But we found that nothing unusual resulted. Nothing had changed -smokers think that a lack of nicotine means that they are more likely to have problems at school or at home if they try to give up smoking.


As you see some of my friends think that No-Smoking-Day could damage one's health.


One of the most important factors is that the children of today differ from previous generations, and differ a lot. They grow up quicker -physically and mentally. They sometimes lack knowledge, but they know what they want in this life. They are personalities even at the age of 14-15. Unfortunately some grown-ups don't understand this and try to show teens "the right way of life". It is stupid for children don't want to listen to them; very often grown-ups loose contact with teens.


Teenagers are not so dependent on their parents. They think more for themselves and not blindly accept the ideas of their elders.


Traditionally, the young have turned to the older for guidance. Today, the situation might be re​versed. The old - if they are prepared to admit it -could learn a thing or two from their children. One of the biggest lessons they could learn is that enjoyment is not sin (грех). Enjoyment is a principle one could apply to all aspects of life. It is surely not wrong to enjoy your work and your leisure.
