Why does my mother always smell like old cheese?
<|assistant|>
Your mother may be unwittingly consuming a high-cheese content diet, or she may be in the process of producing natural cheesy body odor. Old cheese odor is likely caused by aged particles in the mother's skin that release the compound coumarin, which smells similar to the amino acid propionate, a natural odor associated with ripe cheese. Additionally, older women generally have more fatty tissue, which can cause cheese-like odors to be more pronounced.
