Why Do Our Memories Get Diffused Overtime?

i keep coming across in d you know, one nero science book after another, is this idea that a memory also tends to be wildly inaccurate when we a look at it. So why is it that our memories get distorted overtime? I'm notin your scientist here, but i know that myself. Some memories are not really your memories, they are rather some because of some pictures and er in a footo book, or anything like that. And i think the reason for that is that if something happens to you e or like an accident, anything can be anything. It's about how you e how you experience a situation, and then you tell the story again and again and again.
