Abstract
As a cranial neurology expert, I am fascinated by the concepts about smiles stated in the Tirukkural. In ancient times, without medical knowledge or an understanding of cranial neurology, how could Valluvar have stated such subtle concepts? This question inspires me to conduct deeper investigations in scientific Tamil.
