Still, you're proposing highly invasive testing based on a hypothetical problem. You only proposed that there could theoretically be such people — who are these people?
There could be 8 year old boys who have the physique of 15 year old boys — it is possible! — which would prove a safety concern in children sports based on age categories. Do we now, based on that possibility we have now identified, say that age categories have failed, and do we seriously propose replacing them with extensive invasive testing across the board?
