I discovered the ability of my tongue during Biology class. I remember clearly the lesson was on flexibility/differences on human body parts. For instance, some may have looped ear, inward belly buttons, or the fancier one with the ability to twitch their eye brows. This tongue job is nothing, almost half the class could do it. I have met alot of friends who could do it too.
Years passed, I later discovered I could do other stunts. Apparently my tongue could turn 360 degree. Left and right. I was impressed. I am unique.
Then, I got obsessed. I pushed my tongue to the limits and did the above. I have no idea how, I just did it. I can fold my tongue, segment it. Scary.
