Sports are integral part of humans to remain fit and healthy. There are few sports which required more physical efforts and some demands demand sharp thinking. I believe girls should not be allowed with boys as team in such sports which demand more physical efforts like wrestling or rugby, and while playing such games a person could be injured and girls are not much physical strong as compare to boys. For this reason women should avoid such games. However girls could build a team with boys in such sports which required less physical efforts like chess, badminton and tennis.
