Thanks for a very thorough overview of the ways in which we are still learning how amazing our human connections are. Touch and feelings of pleasure are essential to developing compassion. You have stumbled gratefully on one of my favorite topics : our mammalian links to loving kindness. Even if you didn't know a bit about the hormone oxytocin . We know how someone can make us feel. Midwives and wise women hope all of us have the experience of knowing such love and the dire consequences of its absence. In all things, balance and healing takes place now. Be nice,be kind! Blessings for the new year! https://jacqueline-laughlin.medium.com/unsolicited-parental-advice-93b2198a571d
