To begin with I must say that sport is one of the things that always keep people fit. 1 think that everyone must do all he can to be healthy. Physically inactive people get older earlier than those who have plenty of exercises. If you do daily exercises regularly you feel refreshed, have a good posture and that makes you feel well.Wise people say that good health is a great blessing. Everyone should do all possible to stay healthy. Being in good health means having both body and mind in good working order free from diseases and pain. If you want to keep yourself fit, you are to go in for sports. Sport is very popular in our family. My favourite kind of sport is tennis.
