The rate of blinking is often a body language indicator as to one's level of concentration. Fighter pilots blink more often when over enemy territory compared when flying in friendly airspace. This is because there is less crucial information to absorb. The same is true for police officers, attorneys, physicians and the rest of us. A good generalization is that the blink rate is roughly inversely proportional to the importance of the information being observed, absorbed and/or processed.
