However, what we do not know is the fact that when a person blushes, the lining of his/her stomach blushes, too. Strange, right? It is said that when a person blushes, blood rushes to his/her cheeks and stomach. Hence, the lining turns red, too.    2.

Yes, you read it right. We all know that every person on this Earth has a different set of fingerprints. Similarly, every person has a different tongue print also. Now, we just have to wait for the technology that would require us to lick a candy/ice-cream to unlock something. Wouldn't that be cool?
