Touching each other is part of what makes us fellow holobionts, part of the greater holobiont that we call the Ecosphere or, sometimes "Gaia." In his book, "Thank God for Evolution," Michael Dowd doesn't mention the term "holobiont," but he gives us a poignant description of what it means touching each other, starting at page 231
The Furry Li'l Mammal in each of us craves touch and tenderness. Without touch, a baby dies, the human heart aches, the soul withers. Touch is not only a biological need; it is a profoundly elegant and essential form of communication. . . . For millions of years our mammalian ancestors were reassured by parents or comrades not through words but through touch. For 99.9 percent of our mammalian journey, there were no words. The need for touch begins for mammals at birth and continues until we die. . . . There is healing in touch, too. Because tender touch communicates love and care, it triggers metabolic and chemical changes in the body that assist healing. Touching also stimulates the production of endorphines -- natural body hormones that control pain and embrace our sense of well-being.
And, let me add, touching each other means exchanging our skin microbiota: it means exchanging the skills that the small creatures that populate our skin use to protect us from harmful creatures and chemicals. Touching each other is a reciprocal gift, it is a gift of love.
Onward, fellow holobionts!
