I disagree that we should lower the age level. Instead, I believe there should be hard limits imposed on how much kids are able to train any sports under 18. There are many formative experiences and learning experiences that are really, really difficult to catch up on, and we should be ensuring that even athletic kids don’t miss out on these. I’m somewhat fine with junior championships, as long as there are limits imposed there as well, but for any kid who’s made it to the Olympics at 14/15/16, there are probably at least 100 whose childhood was stolen in hopes of making it.Setting the age requirement to 18 years old would do that, but it would also rob many people from being able to build their lives, and would cheapen competitions that are supposed to be a display of the best (natural) athletics in the world.
I say that as someone who moved out on my own at 15 and finished high school and started university at the same age. This was the best (of all bad) possibilities for me, but I missed out on significant parts of a childhood. now, given my family, I never had the chance of having a good childhood, but I would have much preferred being able to have a decent childhood and starting Uni at 18.
