The human body is pretty amazing, and I mean that in the true sense of the word: it’s both impressive and, at times, genuinely surprising. It’s easy to take that for granted, forgetting that our bodies aren’t just what we see on the outside, but a complex, interconnected network of cells, tissues, organs and bones working together in ways we don’t always understand.
It’s just as easy to forget that beyond the obvious differences in how we look, we’re all unique in ways we might never expect—that is, until someone shows off a “party trick” like touching their nose with their tongue. (I pretty much made this my unofficial life mission after watching my grandmother do it.) Some of these quirks are more common than others, but some are the kind of anomalies you’d rarely come across, and those are exactly what this list is about.
