ALT A montage of two combined screenshots of an article on The Telegraph website. The headline says “The surprising habits linked to dementia.” Underneath it says “Having a wood-burning stove.” There is a drawn-style illustration of a wood fire burning inside a cut-away view of a head, as if it were cooking the brain. Text under the illustration notes that there’s good evidence of a link between air pollution and dementia. PM2.5 can be deposited in the brain, causing damage.
