The Smell of Fear

The U.S. Military wants to know if you smell scared.

Now, the US Army is trying to track down and harness people's smell of fear. The military has backed a study on the "Identification and Isolation of Human Alarm Pheromones," which "focused on the Preliminary Identification of Steroids of Interest in Human Fear Sweat." The so-called "skydiving protocol" was the researchers' method of choice.
