It depends what is within the soul, to what projects within the whole of the person; as saying, not everyone can look past the outer garments, and often we're taught to live by our ego in this world....is that correct to think?
So there is a dangerous potential in what I've said for people to become very judgemental, and be blatantly wrong about people due to genetics, and not enough understanding of these differences.
Like any study of biology, everything is not always as it seems... The fluffy caterpillar could be poisonous; the smooth skin could be a snake.
So the crooked nose on its own, doesn't give the game away, it is the spacing between the eyes, the distance between the brow, and the shape of the brow is a huge clue, with it showing many viruses mankind can propagate within themselves.
It's like if you can see the angle of the eye someone glances at others from, that links right back to their soul, and it all shows in it subtle changes to the face over time.
Anyways teaching you to see this isn't a good thing, as there are too many dodgy people out there , and very few who maintain the innocence of a child within their outlook.
