This phenomenon seems to control and be ubiquitary in life, it becomes even more appearent if you view it from a bioenergetic perspective.
We all know that from a bioenergetic perspective, good health leads to more health, energy leads to higher structure, and higher structure leads to more energy.
Ergo, a good metabolic rate influences every single aspect of life, by dictating how we'll react to a situation or problem. If either we have enough energy to overcome it, to then face bigger challenges, or succumb to a challenge due to being in an energetic deficient state, that then leads to an even less of an ability to prevail in the face of a smaller threat.
Perhaps the most influential and powerful people that've existed possessed a high metabolic rate?
