That graph doesn't surprise me at all.
The equator is recognized as the dividing belt between the Northern and Southern Hemisphere.
Just like in the real world, the butts are usual below the belt ---- with some exceptions---- where part of the butts are exposed above the belt.
Forget about Australia, most everything is ass backwards there ----- h*ll, even their toilets flush counter clockwise...
And the boobs, of course they are usually above the belt line ------ but there are some exceptions there as well.
Some boobs wind up below the belt line, due to gravity, age --- and some women having enough kids to field a baseball team ---and all the kids sucking on them...
Of course for guys, it's entirely different. We have both, penis and butts below the belt.....:thumb:
