We have invisible stripes
The human body has a similar stripe pattern as Tigers, we just cant see them. Our stripes, called Blaschko lines, are formed as our cells are dividing and our body is growing in utero. The rows of cells look identical but certain rashes follow the lines, making them visible. They can also sometimes be seen under a powerful ultraviolet light.
Some idiot didn't get the science facts right, there is a DOMINANCE of one nostril, and it shifts every couple of hours to another one, but it sure is not 100% one nostril, in normal circumstances.
