Americans are not growing as tall as their European counterparts, health care and nutrition suspected. It’s odd, but I suspect the fear of being shorter than the French might go further toward promoting universal health care and good nutrition in the U.S. than any of the more important reasons for promoting these things.
I’ve read compelling commentary (which I cannnot currently find) which suggests the massive influx of Mexicans is the reason for our stagnant “growth” in the growth department.
