Sports and exercise tend to go hand in hand.So people involved in sports gradually become fitter.While this can be achieved by dieting and hitting the gym too，sports make this process fun，as the person involved in a sport is so busy enjoying himself or herself that he or she loses track of time.
A healthy mind comes from a healthy body.It is no surprise that since most sports usually involve exercise，it makes for the mind as the feelgood hormones(荷尔蒙) of the body，called endorphins，are released.They are stress killers and bring a relaxing feeling.
Getting better at a sport is a skill that may not have a financial relation to your life，but it can definitely have an impact on the quality of your life.People respect those who show excellence in any field，and sports are no exception.If this is turned into a skill，then it can even lead to ways of developing a career.
Many popular sports like American football，soccer，basketball，volleyball，etc.，are played in teams.This teaches values and skills like leadership，communication，and sacrifice.Not only does this benefit the person in developing a better game，but it actually helps in all walks of life，as these values are essential if one is to lead a good life.
All sports have an outcome.One side wins，and the other loses.Winning and losing is a part of life.Sports teach this lesson to people.Some people glide along as long as there are no hardships in life，but the moment the life is against them，they find their emotional strength decreasing.Sports definitely teach a person how to take losses with grace and move on to achieve greater things in the face of difficulties.
Children and adolescents are filled with physical energy.Teenage is such an impressionable age.If adolescents are given free time they may get involved in wrong activities，may fall in bad company，or may also become antisocial.But when they are involved in sports，their physical energies are used up in a constructive way.
In sports，a person has to make quick decisions depending upon the situation that he is in.Thus，a person who is involved in sports is able to make wise and quick decisions in other areas of life as well.
When something is improving your health，making you physically fitter，earning you respect among people and generally making you feel better about yourself，it is safe to say that such a thing does a whole world of good to your selfconfidence.
Sports are one of the few things out there that do not have any drawbacks.With sports，it is never too late.
