"A teacher affects eternity; he can never tell where his influence stops." As Henry Adams stated, and is the summary of the impervious bond between the characters Mitch and Morrie, in Tuesdays with Morrie. Amyotrophic lateral sclerosis (ALS) often referred to as Lou Gehrig's disease is a form of motor neuron diseases. It is a rare disorder in which the nerves that control muscular activity degenerate within the brain and spinal cord. What results is weakness and wasting away of the muscles. The cause is unknown. About one to two cases of ALS are diagnosed annually per 100,000 people in the US. (Lou) Sufferers will notice weakness in the hands and arms accompanied by wasting of the muscles (Motor). The weakness usually progresses to involve the muscles of respiration and swallowing leading to death in two to four years. When someone is diagnosed with such disorder, it turns their life in unknown directions, and you can either handle it positively and be strong and love through it, or let it waste your life away. In Mitch Albom's Tuesday's with Morrie the main character Morrie Schwartz is diagnosed with ALS, he doesn't let it slow him down in his life; it has made him personally stronger, and gave those people around him a more positive attitude. ALS attacks motor neurons, which are among the largest of all nerve cells in the brain and spinal cord. These cells send messages to muscles throughout the body. In ALS, motor neurons die and the muscles do not receive these messages. As a result, muscles weaken as they lose their ability to move. Eventually, most muscle action is affected, including those which control swallowing and breathing, as well as major muscles in the arms, legs, back and neck. There is, however, no loss of sensory nerves, so people with ALS retain their sense of feeling, sight, hearing, smell and taste. This disease does not affect the mind and people with ALS remain fully alert and aware of events.
