The changes take place in our world. Suddenly, every female human being has super-strength that allows them to lift vehicles, cement trash cans, and other heavy items with little or no effort, and heal from any injury as severe as a gunshot wound in a matter of minutes. But there are no outward signs to the change. Women would physically look the same as they always have. However, due to these abilities, every female will also have better stamina, agility, durability, and slower aging. What impact do you think this will have in various societies/cultures across the world?
By the way, as for future generations, when childbirth comes around, the male baby will not have superpowers, though he has a super-powered mom. And the female baby's strength and healing will increase with age.
