About a story which I remember

I want to tell you about a story that my grandfather told me when I was 12. When I was at school, I used to live with my grandpa during the summer holidays. His house is outside the city, about 60 kilometers away. His house is extremely big and there are a number of various trees. During the day we work in his garden and in the evening he will tell him stories about his army days. I don't know if it was a true story, on the contrary he spoke with enthusiasm and emotion, and I always believed him. He was for 3 years in the Krasnoyarsk Territory. It must have been extremely cold there. Once he told us how he won a competition among soldiers in freestyle wrestling. His opponent was from Estonia and was supremely strong. But my grandpa wasn't a gift either. There was an uncompromising battle between them and my grandfather won. And after the fight, both rivals became friends and shook hands with each other. I remember this story because thanks to sports, you can make friends with others. Both you and others also become strong with such friendly rivalry.
