the masks also deprive children's brains of oxygen, which lowers IQ. Even in the decade prior to covid, a lot of research papers were published showing that schools in high-oxygen areas (such as a mountain valley with lots of trees) earned higher test scores than schools in low-oxygen areas (like smog-filled cities). Some educators even floated the idea of having kids use oxygen masks in between class to 'super-charge' their brains.
