Can you roll your tongue like this? image
If you CAN, then please REBLOG.
This is for serious science! because I have an assignment in my biology class to do a survey on how many people can or cannot roll their tongues.
If you CANNOT roll your tongue like that, then please FAVOURITE this post!
you can de-favourite the post or delete it from your blog in about two weeks if you desire to do so, but I plead you to take part in this survey of serious sience! thank
