Practicing sports is fun and good for your physical and mental health. However, there are drawbacks while practicing a sport, take for example table tennis also known as ping pong. It is one of the most popular sports in China and it is widely known. Ping pong is a fast paced sport which rewards good technique and fast reaction times. During a training session of ping pong the players engage in a dynamic match, hitting and smashing balls everywhere (preferebly on the table ;)) ). As a consequence, at the end of the training set, the floor is completely covered with small ping pong balls… and it is time to pick them up.
