Yesterday when I logged into my Facebook account, it showed a picture I had posted six years back. In the frame, I was having lunch with an old school friend.
It brought a smile on my face.
Interestingly, I had completely forgotten about the lunch. I just couldn’t remember being present when that picture was taken. My brain had conveniently erased that incident from memory.
I am sure it happens to others too. Also, Facebook knows it, so they introduced this feature. Bringing back those lost memories creates a pleasant experience which isn’t much different from the one when you find money in your old pant pockets.
How would it be if we never forgot anything? Why does our brain choose to remember something and spaces out on others? Is there an evolutionary reason behind this behavioural quirk? Let’s explore these questions today.
