I think the lower number of women in high level sport is due to men being noticeably stupider than women. There’s more men than women in prison and the armed forces, both of which have a commendable equal opportunities entrance exam.
To become great at anything takes a very long time doing it, only the truly stupid are willing to sacrifice that much of their life to stupid stuff like tennis.
David Beckham, despite being a thicket, was self aware enough to say, “I done it for ages, so it made sense to keep doing it” when he went to the US to continue playing soccer.
Scholarly, I’m sure you’ll agree.
