I'm addressing this at Americans in particular.
So Josh MF Hoey can suddenly smash record after record at 25 after stagnating or going backwards for years, and it's 'talent never goes away', because he was a high-school champ?
But Georgia Bell, who won silver at the English U17 school championships when she was 14, and literally takes years off from the track (but keeping a base fitness level as clear from her parkruns and such), and she must be doping to come back as a world class talent when training with the likes of Keely Hodgkinson?
