Is Polymarket banned in the U.S.A. and most of Europe or am I reading this wrong?

Looks like mask production didn't take off in Europe even after COVID. Checked the stand in the shop and everything seems to be made in China.

Best take I've read on the trolley problem so far. Someone showed it to a guy who works on trains and hadn't seen it before, and he replied: "The best thing to do is to pull a lever while the train is on the junction, there is a good chance it will derail without toppling over. Even if it doesn't work, it will count when you are on trial."

Recall of kettle-bells because they are radioactive somehow seems very 21st century.
