flip video lesson 3

My personally belief is that people do not exceed there cranial limits.The reason that i think that we do not exceed our cranial limits is because we do not know what our cranial limits are.So how could we know what the limits are if there are none set. If our cranial limits are unknown it is impossible to say what is our cranial limits. I believe many people do not know what cranial limits are so they would not know how to really answer this question correctly as well as i do not. Throught the years of life many inventions were made and many people did not belief they would work and it turns out to be that many were wrong and there have been discoveries made in history.
