According to a study conducted by the University of Toronto that was published in the Neuron Journal, having a perfect memory isn't a sign of intelligence and forgetting things might actually be making you smarter.
Our hippocampus is where all our memories are stored. This part of the brain is responsible for filtering all the information we accumulate and when it becomes overcrowded with details it weakens or removes old or irrelevant details to make way for new information.
The study found that this process helps people remember the bigger picture and forget the unimportant details which is actually better for our brains.
