Why do old people smell so bad?
<|assistant|>
Old people can smell badly for a variety of reasons, including a decrease in oil production in the skin, changes in the circulatory system that affects the ability to remove waste products, and poorer mouth care which can cause a build up of bacteria. Additionally, certain medical conditions such as diabetes or an infected prosthesis may cause a foul odour.
