A system in “neutral” is desirable for physical activity.  It allows for efficient, alternating, reciprocal function in performing daily and sporting activities.   In other words, great fuel mileage with less wear and tear in the long run.  Taking the car analogy one step further, what would happen if we didn’t have neutrality, if we drove for miles and miles with our tires out of alignment?  Chances are we would end up on the side of the road sooner or later.  Well, our bodies are not designed for “neutrality”.  As humans our thorax, along with vital organs are different from right to left.  This affects our “alignment” and may cause us to use our fuel (a.k.a. oxygen) inefficiently.  Lets take a look at these differences.
