Why do old people smell so bad?
<|assistant|>
As people age, the skin and hair begin to produce less oil and sweat less. This causes the body to have less ability to wick away sweat and natural oils which could lead to greater rates of bacterial growth. As a result, seniors could suffer from deteriorating hygiene. The drier conditions, combined with a weaker immune system and the use of medications could lead to increased body odor and bad breath.
