Why do old people smell so bad?
<|assistant|>
Old people tend to have dry skin, which means that they perspire less and therefore don't have as much sweat to regulate odor. Furthermore, as people age, their sense of smell and taste dull, so that unpleasant odors may be less noticeable. They also tend to have an unhealthy gut microbiome, leading to increased odor-producing bacteria.
