How many times do you think that you blink in one minute?
Blinking is a semi-involuntary movement - you can blink when you want to, but also do it automatically, like breathing. We blink about 16 times in a minute, so if you are awake for 16 hours, then you will blink about 15360 times a day - give or take a few blinks.
