While many folks - including me - may be skeptical about this part - the rising occurrence of celiac disease, plus my own experience of my doctor simply shrugging when I asked what might be causing my inflammation, does bear this out to some extent.
My skepticism is also reduced because I remember reading years ago that researchers were surprised to find little evidence of many of today's diseases in the bone fragments of ancient man.
But primitive man didn't live long enough to get these diseases, you might say.
Good argument. But while life expectancy for primitive man was about 33 years, less than half that for modern humans, Sisson points to research that shows that primal humans who managed to avoid disease or becoming dinner for a saber tooth tiger could enjoy healthy lives comparable to today's life expectancy.
So that brings us back to our original question, "What would Grok do?"
Just be sure to ask this question in the proper context.
Ten thousand years ago, Grok would have eaten lots of plants and animals, moved frequently throughout the day, lifted heavy things, sprinted to either catch food or avoid being caught as food, rested, and used his brain to figure out how to survive.
But that was then. If Grok could somehow magically be transported from his hunter/gatherer existence of yore to the comfortable middle class lifestyle so many humans enjoy today, "What would Grok do now?"
Probably the same as most of us guys. He'd relax in his man cave rocking in his favorite recliner in front of the big screen TV watching his two favorite football teams, the Bears and the Lions, with a remote, pizza and beer all in arm's reach, thanking the Great Spirit for the great new life he's found.
And when the new year starts, he'd say to himself, "This loincloth just doesn't fit like it used to. I need to start a diet and fitness program."
