But brain surprises don't stop there. The most profound aspect of human memory is the ability to forget. Yes, you heard that right. At first glance, this could appear to some as a flaw or weakness in our brain's functions. But think about it: how could we handle the overwhelming amount of information stored in our brains at once? Imagine being bombarded with every single event, conversation, and detail without the ability to filter or forget any of it. Also, imagine having to consciously choose what to forget and when. Forgetting allows us to clear out clutter from our minds, making space for new experiences, and focus only on what matters right now. Have you ever seen "The Sphere" movie? It's about a group of scientists who went deep under the ocean to explore a mystical sphere that fell from outer space, which gave them the power to bring their imaginations to life. However, the scientists begin to manifest their fears. This demonstrates how powerful human thoughts can be, often drifting beyond our command.
With all that in mind, reflect on the fact that each person is born with this complex memory system that starts recording every detail from birth to death. As we grow, this system grows too, becoming larger and more advanced to better serve us. Is it possible for something like this to develop within us without some form of intelligent intervention?
The human memory encompasses everything that we experience from birth till death. So everything we visualized, thought about, or felt is stored inside this little organ. Yes, despite its small size, the brain is more than capable of storing an immense amount of information. In fact, some studies suggest that the brain can hold about 2.5 petabytes of data, which equates to approximately three million hours of television shows. That's more than enough to replay a lifetime of experiences over and over again.
But a lot of these stored memories are deeply buried and beyond our conscious reach. Nor do we have control over which memory we can access and when. This is all done by the brain itself without any conscious effort from us. The brain decides which part of our memory to bring up and when. The connection the brain has to our psychology and to our emotions plays a role in selecting which memory is better for us to forget and which memory is important for us to keep. Sometimes even a smell can bring back an old memory, a scene from the past, or even a random thought. But this only raises more questions than it answers. For example, how could the brain do all of that on its own? What kind of complex intelligence is at play here?
What's even more fascinating is the dynamic nature of stored memories inside our brain. Which means our brain doesn't only keep them there, but it rewrites and updates them regularly when needed. For example, if you remember something from your childhood, that memory would come up, and then your brain would store it back again. But this time your brain would update this memory differently because you'd be interpreting that memory from your adult perspective. That old memory would be updated with new perspectives and emotions, while the original memory is kept and stored more deeply.
