Every square inch of our body has about six hundred touch senses. Our bodies are full of devices! If we dig a little deeper, we will find fat nerves. The fat nerve is what separates the nerves from other nerves, causes no collision of the nerves or information mix ups. Nerves are very precise and are very important to our body. In a friction of a second, the nerves are able to travel from our toes all the way to our brain. 

    The pilot, Matt, has to keep track of speed, watch all around him, fly the helicopter and watch his crew on the ground giving him direction to the boys in need of help. He needed all sensors on board in order to rescue these boys. "It is very nerve racking." Four thousand nerves directed his hands while he lowered his rescue swimmer down to the rocks. While a million other nerves were sending him messages.
    In chapter 4, it talks about sensation and perception, sensation meaning touch/feeling and perception meaning vision. In order for Matt to get the helicopter near the boys, he had to use his vision and sensors in his body. Matt had to be able to make small adjustments while paying attention to what was going on. 
    Its amazing how our body works, and I think some of us do not realize what we put our body through and how we do not take care of it sometimes. We are unique human beings! Our bodies are structured to do miraculous things such as rescuing some boys in a high tide, rock crashing ocean.
