Say anything and your racist against Asian people.
There is some similarity in all humans in these aspects. It is understanding in a biological aspect of what changed them is the thing in these ways. Oxygen levels have a large part to play particularly in brain function I believe in this aspect of things this suggest the level of attitude and also other factors maybe be some of what brings about more intelligent people is the reality of things in this way.
This is something that also can some what determine by diet as well too is the thing in ways. But this alone does not do enough in things it just allows for biological matter to develop better in to these forms is all. Take the micro climates of the island in ways. This needed to be applied to the earth in general.
Some things such as colder climate can also so on mean that they or people stay inside more and read more in ways in this aspect of things.
So this is an off shoot of things in this aspect of development that is often over looked by mean in these aspects.
