A Wonderleaf question

a real page from the book
Spicy food feels hot because capsaicin, a pepper chemical, switches on nerve sensors that usually warn your brain about real heat. Your mouth is not actually hotter; your body is reading the signal as danger. Capsaicin is the clever cause.
That is why a sip of water often disappoints. Capsaicin behaves more like oil than sugar, so milk or another fatty food can carry it away better. Meanwhile, your face may flush and sweat may appear, because your body is trying to cool a fire that is only a message.
Taste a tiny peppery crumb, then try water and milk afterward, noticing which calms the feeling faster.
Watercolour scenes, straight answers, about three minutes cover to cover.
