@gungasnake,
There is no debate among the experts, youth is an advantage in gymnastics. The problem is that pushing young bodies so hard is bad for the bodies over the long term, which is why they need to be 16 years old in order to be allowed to compete. Critics say that the rule is unfair to those who follow it because there is no way to enforce the rule under current IOC structure, ans the IOC is not willing to change in such a way that it would become the enforcer.
This is yet another example of why for me the Olympics have become too corrupt to be interesting.
