If you look in the mirror and see those two small dimples, it does not mean you did anything special to earn them. They are purely hereditary. People without them are not less healthy, nor does their absence mean something is wrong. It is simply a matter of how your skeleton and connective tissues are shaped.
For older readers, this can be reassuring. Many people in their 60s and 70s worry about every new spot, mark, or change they notice on their body. In this case, these dimples are nothing to worry about. They are simply nature’s little signature, unique to your genetic blueprint.
