Answer:
Humans have interesting brains that do many things to memories.
With individual memories all jumbled up with each other, it is hard to believe we ever know anything to be true.
New insights into human memory suggest human memories are really a mixture of many non-factual things.
Step-by-step explanation:
The text shows how imprecise our memory is. That's because our brain has the ability to modify memories, fill in white spaces in the memory of a story or a situation, interweave different memories and even delete a memory completely or partially.
For this reason, it is common that we can never remember something as it truly is, what we have is a vague and blurred report that may be totally out of what really happened.
