Final answer:
The statement about a substance that is rubbed on the skin granting immortality could be interpreted as fantastical or commercial hyperbole, depending on its context. It may be found in literature, beauty product advertisements, or fictional narratives that deal with themes of eternal life or beauty.
Step-by-step explanation:
The phrase "You rub it on your skin, and it makes you live forever!" can evoke different interpretations based on the context in which it is used. In literature, such references to eternal life or immortality are often linked to magical elixirs or fantastical plots. For instance, in the historical context, Pliny the Elder's Natural History might discuss ingredients used in cosmetics with an aside on their 'magical' properties. Similarly, literary works can contain dialogue that equates living forever with possessing certain artefacts or knowledge, approaching the concept of eternal life as either a boon or a curse.
In contrast, in the world of beauty products and cosmetics, advertisements may use hyperbolic language to imply that their products can dramatically alter or preserve one's appearance. However, such statements are not to be taken literally, as they are designed to attract consumers by promising extraordinary results. When analyzing the quote in question, it is important to consider the context to determine whether it is from a fantasy novel, a beauty product commercial, a quote from a skincare expert, or a dialogue from a science fiction movie.
