Life is too short to worry about it
Rugby season is hear. I must say I loved playing football but watching my kid play Rugby has been exciting. The great thing about Rugby is that they all get to run with the ball. The Jamborees are two hours long and lots of running. I spent most of my youth running. Running in the forest, running in Track and field , football, soccer, and any were else I could. It keeps the heart healthy. Parents are concerned about injury and they have good reason. I have only seen one injury in 3 years. I think it is because there is no equipment, kids are taught to hit in a way to avoid injury.
