The Percentage of People Who Can Lick Their Elbow

We’ve all heard the claim: “Less than 1% of people can lick their elbow.” It’s a statement often uttered in jest, daring you to contort your arm in an attempt to disprove it.​ I, like many others, have fallen victim to this seemingly impossible challenge. So, I decided to delve into the anatomy and the reality behind this persistent myth.​

My Attempt at the Elbow Lick

First things first, I had to try it myself.​ I extended my arm, rotated my shoulder, and craned my neck, all in pursuit of that elusive elbow.​ The result?​ A whole lot of discomfort and not even a hint of tongue on elbow.​ Disappointment?​ Sure.​ But it fueled my desire to understand why this seemingly simple task felt so impossible.​

The Anatomy of Impossibility

Turns out, our bodies are designed in a way that makes licking your elbow incredibly difficult, if not impossible, for most people. Here’s why:

  • Joint Structure: The elbow joint is a hinge joint, designed for flexion and extension. This structure limits our ability to rotate our forearms inward, a movement essential for getting our mouths close to our elbows;
  • Ligament Limitations: Strong ligaments and tendons hold the elbow joint together and restrict its range of motion.​ These structures, while crucial for stability, prevent the extreme flexibility needed for the elbow lick.​
  • Tongue Length: Let’s face it, our tongues are just not that long for most people.​ Even with exceptional flexibility, the average tongue length simply doesn’t reach for the majority of the population.​

The Myth Busted

The claim that less than 1% of people can lick their elbow is, thankfully, a myth.​ There’s no scientific evidence to support this figure.​ While extremely rare, some individuals possess a combination of:

  1. Hypermobility: This refers to an increased range of motion in their joints, allowing for greater flexibility.​
  2. Shorter Humerus Bone: A shorter upper arm bone can bring the elbow closer to the mouth.​
  3. Longer Tongue: This one is self-explanatory – a longer tongue increases the chances of reaching the elbow.​

For these individuals, licking their elbow might be achievable. However, it’s essential to emphasize that attempting this feat without the necessary flexibility can lead to injury.

My Conclusion: Embrace the Impossibility

While my journey to lick my elbow ended in defeat (as it does for most of us), it provided a fascinating lesson in anatomy and the limits of human flexibility. The persistent myth serves as a reminder that sometimes, the most entertaining challenges are those that defy our expectations and remind us of the incredible complexity and diversity of the human body.​
