Are you careful about the choices you make?
What does to lead a healthy active life mean?
Do you love what you are doing?
How do you feel about your life today?
Ask yourself these questions honestly as you read on and state what factors can influence your health.
Young people face a multitude of health-related challenges: unsafe neighbourhoods, violence, family problems, and chronic, untreated health conditions.
Medicines can stop pain and help people recover from their illnesses.
However, they can also become harmful if they are used improperly.
Using substances that are against the law or are not supposed to be taken into the human body is drug abuse.
Drug abuse, also called substance abuse or chemical abuse, is a disorder that is characterized by a destructive pattern of using a substance that leads to significant problems or distress.
Drug abuse is a very dangerous phenomenon and damages the people's body and mind.
Despite the ample and conclusive evidence that smoking cigarettes regularly can cause such diseases as chronic bronchitis, emphysema, certain types of cancer, ulcer, heart disease, and although the majority of young people can realize the dangers of this harmful habit, many teenagers continue to smoke.
It is well - known that most heavy smokers lead shorter
lives than nonsmokers, and yet a great number of young people all over the world begin smoking each year.
Teenagers can also become addicted to alcohol, moreover, they can this age of AIDS, there are many saocial, personal and emotional consequences for the people who have it or the virus that causes it (HIV).
Unfortunately, teenagers can also get the AIDS virus, that's why it is imperative that they should learn how to make thoughtful, healthful decisions which may prevent them from getting AIDS.
Health involves every area of your life.
Taking care of your health by making wise choices is your responsibility.
Today, more than ever, teenagers should take control of their health.
It's up to them to be responsible for their own life style.
This simple commitment is the first step toward a long and healthy life.
No one else can make this commitment for them.
They are the only ones who can shape their behaviour in ways that affect their health.-
