I like watching all kinds of sports, especially tennis. Roger Federer is famous all around the world, who has been popular for many years. Now he is almost 35, which is the old age for tennis player. Many players choose to quit playing as they are more than 30 and Roger was once doubted by the public. They believed that Roger would not play as good as before, but Roger proved that they were wrong. This year, Roger won two grand slams. He is still the top tennis player. Federer is the real hero in my heart. He not only keeps on playing tennis, but also a good husband and father. He never lets his fans down.
