Cough up your identity. No pun intended.

Just when  you thought we have categorized, extracted, and identified  just about every human characteristic and behavioral trait possible, we might have found another in which to identify you with. Researchers have discovered that the cough is distinguishable among people, and can be recognized correctly just as easy as fingerprint or vein patters are.
It might seem silly to cough for security purposes, and sure will add to the alarming amount of bacteria in the air, but it might be practical in very specific instances, where medical reasons are a factor.

Coughing up who you are.
