Ten small things your body can or can't do. Try each one right now, give it a fair go, then answer honestly. Some can be learned with practice, so answer for what you can do today.
Would you add your answers to our research? It is optional and anonymous, and your result appears either way.
Each step is the share of people with your answer. We multiply them, which assumes the quirks are unrelated. Some are not (people who wiggle their ears are more likely to move one eyebrow, and the tongue tricks travel together), so treat the result as a rough estimate. As responses come in, our own data will replace these figures.
