Why is it taboo to ask a woman her age?

Asking a woman her age can be considered taboo due to societal norms and expectations surrounding youth and beauty. Many cultures place a high value on youthfulness, leading to the belief that revealing age may invite judgments about attractiveness or vitality. Additionally, such questions can feel invasive and imply a lack of respect for personal boundaries, as age is often seen as a private matter. These factors contribute to the sensitivity around the topic.
