why do americans seem to always have thick necks in photographs?
Both men and women. Is it to do with the way they smile/pose for the camera or something? Seriously, I can almost tell someone is American by the way their neck looks in a photo
Car culture is huge in the United States. Most folks I know drive everywhere even if it's only a mile away. Add fast food drive-throughs like McDonald's to this and you get obesity and thick "necks".
