Are We Always Looking at Our Nose?

Your nose is in your field of vision, so you are always looking at your nose.
Luckily, our brains filter out sensory information we don't need.
The ability to ignore expected input is called "unconscious selective attention."
You don't walk around constantly noticing your nose or your glasses for that matter (if you wear glasses) because it's not useful information.
If nothing is changing with your nose, your brain will decide it doesn't need to register it out of efficiency.
It's a Matter of Efficiency.
You don't need to look at your nose or glasses all day long, so your brain filters it out.
You don't need to feel every part of your body 24/7, so your brain filters it out.
You don't need to hear your mom telling you to stop watching YouTube videos and clean your room, so your brain filters it out.
The brain is an efficient and calculating machine that continually tries to improve our efficiency.
If our brain were less efficient, our bodies would have to eat more.
The brain already takes up 20% of our energy even though it only accounts for 2% of our mass.
Sometimes this leads to strangeness, but in the case of our noses, let's be glad for our limited attention and automatic filters.
