Breath is life. We all know this empirically—from direct experience. Ever since we came out of the womb up until now, we’ve all needed to keep breathing. Every few seconds, we bring air in. And breathe out. For the simple purpose of transforming energy. However, this simple act of bringing in oxygen to keep life going—and power our body and mind—has taken on new significance over the years. As my research career developed, I’ve gained a deeper appreciation of the role of energy in driving health, wellbeing, and life itself.
