If you’ve got a teenager that lives in a stinky room or wears some smelly clothes, there IS a reason why they live like that.  They don’t mind the horrible odor because they literally don’t smell it!  A new study out of Denmark found teenagers were less likely than any other age group to recognize the scent of sweat and body odor. Researchers say that could be why their rooms smell.  Basically, they get used to the scent before they even fully recognize it as bad.  Teenagers were also the least likely to recognize the scent of soap.
