I really like sports. But my favorite sport for me is football.
I like to chase the ball on the football field, score it in the goal, celebrate victories with friends, experience defeats, because they make me stronger and more enduring. My father instilled in me a love for this sport. He plays football on a professional level. He often goes to competitions. They and the team already have a lot of victories. Most often I play football on weekends, because not all my friends have the opportunity to come to the field on weekdays.
Friends, do sports, no matter what kind of sports, just to do, because sports are health. No wonder they say: "In a healthy body - a healthy spirit."
