You smell like a Terrorist!
The US is apparently developing technology to detect Terrorists by their body odor. As a teenager, I remember my father telling my when he was in the military (he was deployed to Korea during the Vietnam Conflict) that near the DMZ they were under very strict diets. Basically no smelly foods. The Koreans couldn't eat Kimchi because the smell after eating it stuck around in your sweat for months. If I remember correctly, even the Americans were banned from certain foods. The Koreans complained that our high red meat diets gave us a stench unique to Americans. This was particularly a problem when you were out on patrol and suddenly picked up the smell of Kimchi (something the North Koreans obviously didn't ban. This technology obviously goes beyond diet and gets into body odor as a unique identifier, like your own finger print.

The military’s been after scent-based detection systems for years now. In 2007, Pentagon research agency Darpa solicited proposals for sensors to sniff out terrorists using unique genetic markers found in human emanations. The idea was based on research showing that mice each carried a unique “odortype” that was consistent despite variables like stress, hydration or diet. And odortypes are so powerful, they stick around for around a month after their host body has fled the premises.
