According to new research published in the journal PLoS One people can tell how old you are by how you smell.
Research on all age groups rated 'old person smell' as less intense and less unpleasant than the body odors of middle-aged and young individuals .......... Not only are young people stupid but they stink too.
The body odours of non-human animals contain many chemical components that can relate a variety of social information, like a Facebook for the nose. Hold on while I just go and pinch off a status update.
These chemicals change throughout the life cycle and humans can detect many of them much like other animals to find a suitable mate, identify age, avoid sick people and to tell from friend or foe .
The research was narrowed to one individual and it was found that because he was so old his odour actually made people aroused, they called this the 'Knudsen effect.' Weemen it seems wanted to bury their faces into his armpits and would do anything to be with him. Lesbian weemen wanted back on the pogo stick as long as it was his, straight men went ghey for a day and ghey men were um like totally ghey.
Research was hampered when Old Knudsen who did not want to be rude accommodated many of the test subjects and ended up smelling like them.
Those old people who can't smell their odour and so douse themselves in horrible perfume don't count, when you get old go natural the Old Knudsen way ....... manufactured smells are for the weak as is wiping.
