Your senses of smell, taste, hearing, touch, and sight serve a greater purpose. They’re not just for breathing in freshly baked bread, swishing a glass of pinot noir, listening to Sgt. Pepper’s Lonely Hearts Club Band, squeezing the Charmin, and laying eyes on the love of your life. All wonderful pursuits of course, but the most vital task of the five senses is to alert our brains when something is amiss. Do you smell something burning? Check the stove. Do you taste something rotten? Spit it out. Was that the shrill whistle of an approaching train? Get off the tracks! Feel a prick on your arm? Get away from that beehive. Is he holding a gun? Run.
