Forgot to pick up your dog from doggy daycare? Feeding mittens slipped your mind again? Drew a blank on cooking something? There's no need to worry about premature memory loss just yet as it turns out it's just how our brain works. Although the human grey matter is capable of storing around 2.5 million gigabytes of memory, we tend to forget memories that are similar to each other (feeding the cat for instance) from time to time, to remember the novel or more interesting ones better. However, these little losses of memory can be a cause of some pretty funny stories (for you and your friends, not for Mister Mittens sadly).
