Neuroscientist Dr Charan Ranganath says it's actually a good thing that we don't remember everything.
Dr Ranganath is a Professor of Psychology and Neuroscience and director of the Dynamic Memory Lab at the University of California.
His book, Why We Remember: The Science of Memory and How It Shapes Us, shines a light on memory and the roles intention, imagination and emotion play in our brain's decision to store certain information.
He says that sometimes memories are purposefully innacurate, and that we've evolved to ditch some memories in order for us to hold onto crucial bits to guide us in the present.
