I bet the Zombie brings Hollywood to mind. Well that’s on the extreme part. I’m talking on a normal level. Have you given a thought to how much of your activities you actually pay attention to? Do you realize that a lot of the things we do on a daily basis are actually carried out on autopilot? You don’t realize you’ve done it till after:
Ever been driving a car and realized you haven’t actually been aware were you were the last few minutes?
Ever finished a bowl of cereal only to ask yourself when you started?
You could explain it simply as Muscle memory. Those memories of frequently enacted tasks for your muscles all stored up in your brain. It really can help you become very good at something through repetition. Your muscles just take over. Like you’re a zombie.
