Why do things blur when in motion?

Think of your mind’s eye like a canvas where your brain is constantly painting on it by continuously gathering light via the eyes.
But whatever it paints, it fades really fast. You can see this effect by closing your eyes and observing how everything kinda fades out instead of disapering instantly.
So your brain has to constantly paint to maintain a stable image. But if an object moves around too fast, the latest instant that the brian paints is smeared over that disapering afterimage of the previous moment, resulting in a blurred image.
Because the nerve impulse moves only as fast as 100 meters per second. After that brain also needs time to process the impulse.
So if anything goes very fast. Nerve impulse from the last frame is still on the way and the thing moves. The next frame has the thing at a different position so our brain cannot really visualise it properly going from point A to B. As a result what we see is blurred.
