Future: Target Advertising By Body Odor

Telegraph: "Researchers have developed a way of analysing the traces of scent that every person leaves behind. [They have] found a way to collect samples that are as free of contamination as possible and analyse them using an "electronic nose" that breaks the scent down into its component chemicals. The technique is already being considered for use with forensic evidence such as DNA and fingerprints. Body odour could also be used in biometric passports."

Wouldn't it be great to flash in-store deodorant ads to people who need one right away?
