It only makes sense if you grow up with Fahrenheit. Otherwise Fahrenheit isn't how humans feels since most of us have no concept what these number mean.
If I would just go with 0 - cold 100 - hot I would assume 50 - perfect. But 50 is still chilly. 70-80 feels like it should be getting hot but that's the most comfortable temperature.
Sport is such an unfair world, trying to find equality and justice in it is futile. We don't want kids taking growth hormones to boost their chances of making it into the NBA. But that also means we crush the dream of plenty of people. Athletes with asthma can't use their inhaler under certain circumstances. A few years ago an UFC fighter with Asthma got his win overturned because he used an inhaler inbetween rounds.
There was a huge discussion about allowing prosthetics in "regular" competition. Turned out at the time that proshetics weren't advanced enough to give an advantage. But I think we all know that this is only a matter of time. And eventually a hard ruling needs to be made that dictates in which direction sport goes.
Banning athletes who take as many hormones, hormone blockers, and other mediaction as transwomen usually take is 100% something that needs to happen. Especially considering that in certain leagues the usage of these substances is the only reason that transwomen are allowed to compete. That feels against the spirit of sport and TUEs. But untill more data exist, I doubt a useful ruling can be made.
What I don't like about the whole discussion is going for the "They aren't real women" argument. That feels degrading and hurtful for everyone involved. I don't want cis or transwomen to have to undergo inspections to determine their gender.
