Why do old people smell so bad?
<|assistant|>
Old people usually produce less perspiration than younger people, and their hair and skin produces less fat, which is necessary for releasing and dispersing body odors. Additionally, due to weakened immune systems, their skin can become dry and flaky, which traps bacteria and can create an unpleasant odor. Lastly, older individuals often take more medications that can result in smelly sweat.
