I agree with Synonymous that reporting someone's age allows the reader to neatly pigeonhole that person and apply hackneyed stereotypes. However, stereotypes should be challenged. Labelling people by age is also carried out by calling them pensioners. Even though pensions may be claimed by people in their 50s, the first idea is 'old age' pension, (happily now, better known as state pension). People are, apparently, avid to know a person's age and some are rude enough to ask outright. I don't ask anyone (including children) how old they are. I think it's because my dad was on a lifelong hobby horse about irrelevant and intrusive, personal questions and partly because I'm not particularly interested. Sometimes, I tell myself that I'm not interested enough. ?
