So there you have it. We take a little pain and our bodies reward us for it, instead of punishing us for our pleasure. We take a little pain as a culture and our ecosystems reward us for it, instead of punishing us for our greed. We take a little pain in order to stay above the grass, as a species, for just a little longer. Until one day we realize we’ve been using the wrong language around all this. What we called “sucking it up” is really just “pulling together.”
