Not really a fan of the word "synergies" but when it is appropriate I use it. As you know I've been reading the Your Survival Instinct Is Killing You (blog post) personally and The Remote Facilitator's Pocket Guide (blog post) professionally. Interestingly enough, both are talking about how social fears or work stress can lead to problems. In the case of the former book it is focusing on how the survival instinct can turn in to maladaptive habits. In the latter book it talks about how social pain is the same as physical pain in that the same centers of the brain light up to process it; and therefore being exluded from participation in remote meetings can feel like physical pain to people.
Not earth-shattering revelation but the degree to which our bodies impact our mind, and our mind our bodies is an increasingly fascinating topic to me. And it is fun to find this type of unexpected synergy between books I'm reading for different purposes. Far out!
