From the irregular data I received from the ruler lab, I disagree with the claim of humans being similar to machines. Although we do have reflexes and take certain time to react to what our eyes perceive and how our brain processes signals, our reaction time do not follow a pattern enough to suggest any kind of mechanical behavior that repeats processes precisely. In other words, differences in reaction times to ruler drops and lack of improvement with practice indicate that the control of muscles by the central nervous system is not similar to a machine but purely due to action and reaction every time.
