25+ Freaky Yet Amazing Facts About The Human Body

It probably goes without say that when we’re asleep, most of the time our eyes are closed. You may have seen someone that is deep asleep with their eyes half-open (and it might weird you out). But how about when we’re awake? That’s right, when we blink, our eyes close, even if it is momentarily. Blinking means our eyes are closed 10% of the time that we are actually awake.

If you do not believe us, it is true. In average, we blink approximately 20 times per minute. That sure does add up over the span of hours. Of course, some of us have longer blinks than others or tend to blink more or less often. Therefore, this amount of time the eye is closed is an estimation and will vary per person.
