An average man at age 50 still has more lung power (o2 sat) than an athletic woman in her 20s.
The very fact most women do not truly understand just how much stronger men are over women, tells me almost none of them have ever really experienced a man’s 100% unrestrained physical violence - you know, like they’d use against another man, an equal. Not that I want that, women really just think their experience is universal. It is not. Men are quite stronger and the few women who have felt it, undiluted, know it to be very true. Life is not a DEI Marvel movie.
To paraphrase the character Jesse Pinkman: “Science, bitch!”
A few years ago I read about a female MMA fighter going against a man pretending to be a woman. After the match ended (I think the female quit the match) she stated that after she took the first hit she thought she may die. She said she had never been hit that hard in her life.
