Did You Know: Every day we breathe over 23,000 times and move over 400 cubic feet of air. In the 2 seconds it takes to inhale, molecules of odor flood through our systems. Many of these molecules are capable of triggering biochemical changes in the brain and body. The reality is that we need only eight molecules of a substance to trigger an impulse in a nerve ending. Most interesting is the fact that the biochemical changes can occur below the actual threshold of conscious smell because it takes forty nerve endings becoming active before we “smell” something.
