Did you know? there is actually a word ‘Tongue Print’?
Yes, like ‘Finger Prints’, every human being has a unique
tongue print that can be used to detect suspects in case of any investigation. (So,
don’t keep your tongue hanging around while walking *wink*)
Interestingly, in a human body, tongue is the only organ that has muscles,
not attached to both ends! (Well, dogs have them too, but all humans are not
dogs… right?)
