I disagree with your comments about American dentition. We have way more people with “Meth Mouth” than snaggled teeth. It is hard to believe that their black, rotted stubs used to be teeth...
the UK must be way fatter than my time there for a period in 1987 when the people were normal sized though not as thin as the French
here in Middle Tn, in some lower income counties I would wager 70% of women are overweight and maybe 40% technically obese...say 50 pounds overweight
and about 10-15% are morbidly fat...as in waddling with aprons...amazing
men run the fat thing at about 1/3 the rate the women do...at most...maybe even 25% the rate
blacks and latinos...well..to be kind..it's near universal...non fat black or latino women are the exception not the rule
in richer areas like Belle Meade or Green Hills...not many fat women
out here in Williamson county...highest cost adjusted mean income county in the USA...a bit more chunkies but not an epidemic like elsewhere
I traveled out west this summer extensively...higher altitude less weight...easy enough
and once again minorities ..which means basically Indians and latinos in the high west..who are hard to tell apart at times...heavy and the women much heavier
whites in the mountain west though heavier than 40 years ago were not as heavy as southerners or midwesterners but altitude does help...no doubt
time I lived in Bogota was the thinnest I ever was...6'5” and 177 pounds
oh well...the health problems coming from all this are just off the charts
bones, pancreas, kidneys and cardiac and ...almost for sure at these weights...diabetes
sad that in the land of plenty there is just too damn much and folks have lost discipline meanwhile folks truly do go hungry in places...not like before but still there is hunger and children die from it...most often exacerbated by war
