| Blinks can take several forms. Besides
the blinks that wash the eye, there are those associated with unexpected
circumstances (such as loud noises), as well as the voluntary flaps of the
eyelids that may express anger or incredulity. Another type, the spontaneous eye
blink, is neither voluntary nor reflexive. Most blinks are
spontaneous. Mere eye-rinsing requires a blink no more than once a minute; yet most people blink around 15 times a minute. Why do we blink so frequently Apparently there is a direct relationship between spontaneous blinking and the mind. Scientists can now discern how the frequency and duration of blinks vary according to whether a person is alert, bored, anxious or concentrating. Studies show first of all that we blink less when we are most alert.
