Okay kiddo, let's talk about professionalism in rugby union. You know how you go to school to learn and your teachers get paid for their work? Well, in the past, rugby union players only played for fun and didn't get paid for it. But now, they get paid for playing because it's their job.
Being a professional means that you have to be really good at what you do, and you have to work really hard to keep getting better. Professional rugby players practice every day to make sure they're ready for games and tournaments. They also have to take care of their bodies by eating healthy food, getting enough sleep, and avoiding things like smoking and drinking too much alcohol because those things can hurt their performance.
But being a professional rugby player isn't just about playing well on the field. It's also about behaving well off the field. This means that players need to be respectful to their teammates, opponents, and fans. They have to follow the rules of the game and not cheat or do anything dangerous to other players. They also have to be good role models for kids who love rugby and look up to them.
Overall, professionalism in rugby union means that players are paid to be really good at what they do, work hard to keep getting better, and behave respectfully both on and off the field.
