But like most Alexandrian movers and shakers Clement was Greek, and haven't you seen Hercules on TV? As to body type Greeks tend to be very stocky and have always been good at hand to hand. Besides, you can't pick a guy at a late time in his life and compare him with yourself in your prime. What if the guy was an expert at pankration in his youth? And the idea they "we're bigger now" does have an element of truth, but not as much as some people think. The volcano statues of Pompey have shown us that the people who lived there then were bigger than the people who live in the same area now, and Roman legionaires had to be at least 5 foot 9 before they could inlist. And if you get to take your gun, then it's an escalation that moves away from personal manliness to technological advantage.
However, your data is skewed because it only examines those famous for their physical stature and then presumes that same nature for every Greek. There is no evidence that Clement was of campare to the mythological Hercules, or Pompey.
Secondly, it's not escalation. He can bring his prized beard, I'll bring my A-5. Fair to me.
Thirdly, I'm confident I can beat him in his prime. A man of 5'9 is of average size. I am a full 7 inches taller than him. The fact that he might be stocky is of little consequence. As a result of my Germanic heritage, I am broad shouldered and broad chested with a strong lower body.
Call his agent and get him to the States, we'll thrown down right here right now.
