Americans are bigger than ever - taller with enormous strength (think of the knock-out game that can kill with one blow). And yet we see a constant dumbing down of the average American. This sounds pretty bogus to me.
Or you are seeing a trend back to our roots
Different people groups needed different skills to survive, and one people group has re-isolated by choice are they just returning to that need
actually the tallest people are from the Netherlands.
With all the illegal immigration Americans are shorter.
“Americans are bigger than ever...”
Horizontally too.
