My idea of hunter-gatherer fitness is something optimized to give all you have before you&#x27;re 40. Something optimized for violence (men) and procreation (women). That&#x27;s stupid.<p>We didn&#x27;t evolve to live as long as we do today. We didn&#x27;t evolve to eat what we&#x27;ll have to eat to sustain a population of trillions. If we strive to be what we evolved for, we&#x27;ll go backwards. We should strive to be what we <i>want</i> to be, what we <i>can</i> be.
