Interestingly, you can discover what the sensation of having two brains is like. When you are driving, particularly on a trip long enough to be boring, you can swich driving arms ... and end up switching brains!
We have trained both sides of our brain to handle this skill. If you have ever driven right past your destination or your turnoff, it may be because the wrong side was in charge.
Your analytical half wouldn’t make that mistake. But the dreamer in you always has time for such lollygagging.
It’s also one of the reasons our hands do odd things while we’re driving. The other side of the brain likes to stay busy.
