senses and stuff !!

Our sense of smell is actually a lot more powerful and a lot cooler than people think. Studies that were conducted have shown that people can identify people by the scent of their body, and can even identify a criminal in a lineup. Also, smelling the sweat of someone from when they were feeling a strong emotion can trigger a similar feeling in those that smell it. For example, sweat collected from someone right before they went skydiving triggered activity in the amygdala, which processes fear, in the brains of those that were smelling it.
