I guess we are resigned to the fact we are not symmetrical. I tell all my patients in 35 years of practice, I have not met a perfectly symmetrical person. I just read an interesting article in the Plastic and Reconstructive Surgery journal.
It had to do with symmetry in our face. After analysis of thousands of facial photos they noticed that the left side of the chin is weaker or less prominent than the right side. Why is this so? No one knows but it may come into play when doing a chin augmentation or a Rhinoplasty.
