I mean, wasn't there a thing a few years back where someone found a completely undiscovered tendon in the human knee? If something can exist close to us (can we call it close if it's literally inside of us?) and yet remain hidden for that long, who knows what other discoveries we might be overlooking.,(reply>), Hahaha. "huh where'd this other nostril come from? That's weird. Wait, everyone has one?" 😂
