Does every person have a unique tongue print?

I believe that 25 percent of a single person is unique. The other 75 percent isn't, because you are influenced by the people around you, the media, and other various factions.

no no

In scincere, not joking response: pride

Every human has a 'tongue print', similar to fingerprints.

This question is currently impossible to answer. We don't know if there are even any other forms of life out in space.
