Finger Printing
Look at the palm of your hands and your fingertips. You will see patterns of ridges that are called fingerprints. The natural body oils and sweat collects in these ridges of the skin so that when you touch things, you leave behind an impression of your print. Fingerprint ridges are useful because they give your hands a better grip when you pick something up. But since fingerprints are unique, they have also become a common and foolproof method of identification.
