An interesting observation related to this is posture.<p>The posture that show higher status, straight back, looking to the front and not down, relaxed muscles, etc.. need less energy and is better for your health.<p>Another interesting though is how good food makes you bigger an taller.<p>So, however is low in the hierarchy, is always less strong and in worst shape, what makes them to get less food, and so on.. It&#x27;s easy to see how a feedback of this kind begins.<p>Of course, all this is carry on to the next generation by several dynamics.<p>I try to remember all this when I hear how some communities are hopeless or just &#x27;don&#x27;t want to work&#x27;.
