Why do old people smell so bad?
<|assistant|>
Old people usually have sweat glands that are less active than they used to be, which makes them more prone to body odor. Their skin is also thinner and may sweat more than when they were younger, so whatever they sweat out, is more readily detected. Additionally, some diseases of old age can affect hormones that control odor, leading to more prominent body odor. Many older people also suffer from dementia or Alzheimer’s, which further hinders their ability to maintain personal hygiene and control the smell from their body. Lastly, old age often means more physical debility, making showering, shampooing and other routines of personal hygiene a much bigger struggle.
