Why Do We Blink So Frequently?
"We all blink. A lot. The average person blinks some 15-20 times per minute-so frequently that our eyes are closed for roughly 10% of our waking hours overall."

Why do we blink?
"We have to blink to cleanse and moisten the eye."

Default mode network
"In neuroscience, the default mode network (DMN) is a network of brain regions that are active when the individual is not focused on the outside world and the brain is at wakeful rest."

Why Do We Blink?

THUMBS UP IF YOU ARE NOW AWARE OF YOUR BLINKING!!!

[TommySasaki]

Dammit now I'm blinking more than I should.

[Rem_NL]

I don't like it when I am being made aware of my breathing and blinking.

[Ayplus]

Lol this video made me blink more while consciously trying not to

[dylanford]

is it weird that i laughed every time i blinked whilst watching this?

[cameronphillips]

I feel like I'm blinking loads now

[dcordin]

I always thought blinking was primarily to keep the exposed part of the eye moist and to clear micro detritus away from the lens to ensure clearest vision at all times. I guess it is a good thing I didn't become a biologist.

Logically you never watch a full movie... You miss most of the part blinking!!!

[zekeski]

i find these kinds of videos funny.. why we blink, breath and clears throat.. it make me concious everytime i do it. and reading at comments. most if not all are having the same problem.. hahahha

[Revan]

You forgot one thing to mention in this. We also tend to blink when the word "blink" pops up in conversation... so fuck you for making blink so much more than I needed today.








I love you guys.

It's painful how aware I am of my blinking now. And I'm only 20 seconds in. It's like whenever I think about breathing I feel like if I don't concentrate on my breathing and breathe properly I'm going to die somehow. Our minds are weird. ;[

[SinerAthin]

All this talking about blinking suddenly made me super aware (and uncomfortable) of my own blinking, dammit.

[BandltFood]

I have to say, I freaking love Trace.  He adds some serious humor to this channel.

[HansPeter-qgvc]

10-20 blinks per minute with eyes closed for 0.1 s each, add up to 1.67%-3.33% of the time, not to 10%.

[TechnicallyaNomad]

Don't blink. Blink and you're dead.

[grannysvids]

Now I'm blinking more than ever! Thanks Dnews.

[americannerdproject]

Why can't we have clear eyelids so that creatures in horror movies can't get to us!

[shonenamv]

[Michacanx]
