theres a condition called Congenital Adrenal hyperplasia, I know a woman who had it, she was born in 1938, they didnt know what sex she was when she was born, the condition blurs the lines genetalia wise.
She was brought up a girl but she had masculine traits, at school she was 5,10 when she was 12
She could fight all the kids at school including all the 14 year olds
She lived her life as a woman but her brain was always male, she could re-wire a house, do all the plumbing, install a gas boiler and re-build scrap Land Rovers and sell them on.
I looked after her during the last two years she was alive during covid lockdowns
I asked her did she have any regrets in life, she said "only one, being born"
Sad...
