We go from 4 feet tall to over 6. Our shoe sizes can go from 3 to a mens 14. We don't all wear size 0 clothing, some wear sizes as big as 20 or even larger. Some of us have A cup boobs, while others have natural D+.
Saying that on average Asian women are shorter and smaller than other women now is like saying that race has a correlation with intelligence.
