How Smell, Taste & Pheromone-Like Chemicals Control You

This episode explains how we sense chemicals through smell, taste,
and pheromones. How things smell and taste and chemicals in the
tears, breath, and on the skin of others have a profound effect on
how we feel, what we do, and our hormones. I explain the 3 types of
responses to smell, the 5 types of tastes, the possible existence
of sixth taste sense, and how the act of sniffing can make us learn
and focus better. I explain how smell and taste reflect brain
health and can assess and even promote brain regeneration. I
discuss how eating specific categories of foods makes us crave more
of those foods, including how to make sour things taste sweet and
develop a heightened sense of smell and taste.  Read the full
