Motion sickness.

It is not so important to act on a constant basis.  
 
People who are in constant motion are really going no where.  
 
In a state of motion there is a lack of insight into what is really going on.
 
In a state of motion life can trip us and cause us to lose our balence very easily.
 
In motion there is no center, little stability and plenty of reason for a person to go astray.
