The good news is that, if left alone, your mind tends to take replay breaks.
The bad news is most websites have a constant stream of information.
There’s the “infinite scroll” design of most social media sites.
While these design features keep you “engaged” they don’t give your brain much time to sort, store, or make sense of what you’ve encountered.
At the very least, this can lead to memory failures, especially for fine-grained details.
