Tuesdays with Morrie is a story of how real-ilfe Professor Morrie Schwartz taught and changed the world until his last  breath. At an old age, Morrie fell into illness that attacks the neurological system of the body called amyotrophic lateral sclerosis or ALS. The author, Mitch Albom, describes the illness as melts your nerves and leaves your body a pile of wax. A person could be alive and breathing, probably can still blink, but can no longer move his body.
