Rolling Your Tongue

The ability to roll your tongue into a tube, like a straw, is determined by genetics, but not my one single gene as textbooks still cite today. However, it is most likely determined by a batch of genes. Out of 33 people who couldn’t roll their tongue, only one of them was able to do it after a month of practicing, strongly pointing to genetics. It’s not a life-changing ability, but interesting nonetheless!
