If you can do these things, you are among the unique people
The human body is weird, that's an undisputed fact. The thing is, a surprising number of our bodies are even weirder than the rest. There are tons of neat, quirky physical things that only some of us can do. For example, twelve percent of women can actually see 99 Millions (!) more colors than the rest of us, but that's not something you can try. However, rolling your tongue or moving your ears is definitely something you can and will try in the next few minutes (trust us, no point to resist), so before you scroll down make sure nobody is watching because it very likely that you're about to make some silly faces and even sing something from a musical.
