Every person has a unique eye and tongue print.

  1. ears, too – And I think everyone has a different shape to their ears, too. What with all those folds and cartilidge, it’s no wonder.

  2. Forensic Science – I did a course in forensic science not long ago. Any part of your body that has skin on it has different ripples and ridges all through it, allowing nearly any part of your body to have a print. There is actually a study of lip prints, called cheiloscopy. Some guy’s ear print managed to get him convicted of some crime.
    Eyes are different from all the pigmentation and veins and things within the eye. That’s why movies with high-tech corporations in them sometimes have retinal scanners. I don’t know if they would be able to fool them with a coloured contact though…
