等我認真答你,其實係基因遺傳。
東亞人呢條基因唔運作,所以無臭味。
佢地係天生就有體味,呢個唔係歧視 係有科學去實證
A specific gene, ABCC11, is largely responsible for body odor in the underarm area, particularly the presence or absence of noticeable odor. A mutation in this gene, which is more common in East Asians, leads to a reduced ability to produce the odor-causing molecules in underarm sweat.
