The smell

Smell influences human feelings and emotions in a tangible way and has dramatic repercussions on psychological, sexual, and emotional behavior because the sense of smell is linked to hormone activity and neural circuits in the human brain. Without smell, our lives lose much of their beauty and joy. Every person has a "smell passport" that distinguishes them from others. And the smell passports play a central role in shaping the social web that connects people to each other, as well as helping infants recognize their mothers by their body odors. This comprehensive study is worth reading because it delves into the details and theories that form my theses on smell and scent not only in humans but also in the worlds of animals and plants.
