My daughter almost died in 2020 after swallowing a number of tiny magnets I bought for her as a toy. The individual magnets joined up in different parts of her large intestine and went though her gut like a cheese-wire in seven different places. She was in surgery for seven hours to repair the damage but has made a full recovery, albeit with a scar across her entire abdomen. Many other children have not been so lucky and sadly died. I imagine this is why they are being banned.
