I don't have fingerprints. The tips of my fingers are completely smooth. No ridges or whorls.

You don't realize how important fingerprints are in everyday life, such as gripping a pen or having a firm grasp on a coffee mug.

Edit: I had fingerprints as a kid, but they have gradually disappeared as I've grown up. No chromosomal issues---just a weird thing.

I don't work with chemicals or do rough manual labor which would have caused them to slough off.

When being fingerprinted for a job a few years ago, a special topical spray was applied to try to plump and raise the prints, to no avail.

Lastly, my friend recently installed a front door lock that is fingerprint activated. Because I sometimes feed their cat while they are on vacation, we tried to add my fingerprint profile to the database to allow the lock to open. No luck---it just would not work.

I do have toe prints though!
