User: Can you tell me about Rugby Union?
Assistant: Rugby Union is a 15 player a side game played around the world. The sport was created during the 1800s in England when, during a game of soccer, a player picked up the ball and starting running with it in his hands. Rugby is most popular in commonwealth nations however has been gaining popularity in other countries such as USA and Japan. The game is played in two 40 minute halves with the winner of the game ending up with the most points. Points can be earned by grounding the ball over the try line in the other teams territory or by kicking the ball through the posts on either end of the field. The game is notorious for its aggression and tackling which can result in injuries as the players don't wear helmets or body armour like in other sports.
