Why does it help to rewatch a video?

Rewatching any video of the program can only benefit you. You’ll be surprised by how many things you’ve missed the first or second time you watched it.
Why do we miss out on important information?
As we listen to a video, a particular idea will catch our interest. When an idea draws us in, we focus on it for a few minutes while the video keeps playing. During the brief time we zone out, we miss what’s being taught. It’s like momentarily muting the video.
The next time you watch the same video, you will not need to focus on the same idea, so you will consciously hear what you missed before.
