Interesting observation; what do NYers look like, en masse?
They look like a population melting pot representing many ancestral immigrant cultures as I always understood New York to comprise.
You know, pronounced facial features such as jutting foreheads, broad and high cheekbones, large eyes spaced close together or far apart, distinct noses, lots of hair and angular shaped beards & mustaches. Did anyone watch the supporting cast to old Frankenstein and Dracula flicks?
Good grief, I just did an image search of modern east/west/central European populations and even they look generically pretty. What's happened to the unique features of our world population? Crap! We've run out of character actors.
