You are what you touch


Fingerprints, as we know, vary person to person. But now, your germs could nail you.

The bacteria that live on people’s hands can be unique. According to Proceedings of the National Academy of Sciences, forensic folk will soon be able to “type” your crud and trace it to you.

Researcher swabbed a computer mouse and compared the bacteria with that on the hands of the owner and 270 randomly chosen people. The owner’s collection matched the mouse.

This can also match a person to fabric he or she touched.

The average hand contains 150 kinds of bacteria—only 13% of which would be shared with any two people.

Ewww…and hmmm, interesting.
