text: The article states that Jillian has experienced a decrease in performance, but, as we all can attest, a decrease in performance can be attributable to multiple factors aside from hormonal changes such as age and many within the control of the athlete such as a reduction in the frequency and intensity of training. While your point about European women raising the competitive bar is accurate, it was raised under the assumption that they didn't not have a biological/chemical advantage that could only be obtained by their fellow athletes by breaking the rules. Mental toughness is a part of every sport, but when a competitor potentially possesses a biologically physical advantage that another competitor could only obtain by cheating, the impact chips away at the implied level playing field. While I appreciate the desire to accommodate Jillian, is it being done at the detriment of biologically natural women and girls?
