Difficult people can leave lifelong scars on the people they have bullied.
Bullying is a distinctive pattern of deliberately harming and humiliating others. It's a very durable behavioral style, largely because bullies get what they want—at least at first. Bullies are made, not born, and it happens at an early age, if the normal aggression of two-year-olds isn't handled well.
Sports are more than just fun and games. From schoolyard chants to Super Bowl championships, playful competition finds its way into nearly all aspects of culture. Fighting to win draws on cooperation, concentration, coordination, and creativity—things worth striving for in their own right.
