About a decade ago, neuroscience began probing the cause of this excessive mind wandering, and it seems to be the default state the mind goes to whenever we lose interest in what we are doing or become tired. And now thanks to all of our modern marvels we now have the attention span of eight seconds, so now we are almost never here in the moment! The purpose of this wandering state seems to be so we can decide whether our reaction to our spouse this morning was warranted. However, this program is broken, so instead of thinking through the issues at hand and drawing helpful, insightful conclusions, we ruminate repeatedly over situations, conversations, and even a single sentence said to us ad nauseam.
This reptilian brain of yours, is the seat of your unconscious and can process more than 200,000 bits of info per second! That is a lot of processing power. So about every eight seconds, or whenever you get bored it takes over grabbing memories from your past, speculating on your future, and scanning your environment for danger, which could mean just a dirty look. This so constant that it becomes an energy you can actually feel in your physical body, like an undercurrent of anxiety or worry, even though you may not be aware of it. Being distracted by all this internal noise can result in your moving about restlessly, recklessly, dropping things, or even being a klutz. The most common symptom, though, is that it leaves you absentminded and forgetful.
