Every summer, when Taipei weather gets stultifying, it is hard for pollution left by cars and motorcycles to disperse. The environmental protection administration will issue warnings to old people and children to stay indoors as much as possible, because according to statistics they are twice as likely as others to get pulmonary infections.
