Was listening to an American history podcast (the dollop) about the radium girls. They wore uranium infused lipstick because it glowed and they thought it was cute. They licked their fingers regularly to help apply uranium dust to things.
While their male supervisors were wearing full lead suits totally for no reason and let those girls do that.
Many of them lost their jaws. There was a suit filed that they won, but every single one of those girls died before they could collect the money.
The suit led to a law establishing workers' safety rights, so it wasn't all bad. But that law was definitely written in those girls' blood.
Look into the death of George Washington. His doctor responded to what could have been a mild cold by taking a liter of blood 4 separate times from him. Washington very well could have recovered if he was just left alone.
Oh, and the doctor somewhat realized his mistake and tried to put some of the blood back after(!) Washington expired, with the logic that if blood loss killed him giving it back should revive him.
So yeah. Pumping blood back into a dead man. That was done on the founding president of the United States.
