Scientists say people can identify the age of other humans based on differences in body odour.
Japanese even have a word for the so-called 'old-person smell' - it's kareishu.
Latest research shows individuals rate this odour as less intense and less unpleasant than body odours of middle-aged and young people.
Body odour can also help people avoid sick individuals, pick a suitable partner, and distinguish kin from non-kin.
