The document discusses the novel Tuesdays with Morrie by Mitch Albom. It follows Mitch as he reconnects with his former professor Morrie Schwartz, who is dying of ALS. Morrie teaches Mitch about what is truly important in life as his time draws to a close. The document also discusses how the novel and a textbook both address aging and facing one's mortality. It provides an example of how Morrie initially reacted with shock and denial to his diagnosis, but later accepted his condition, as outlined in Elizabeth Kübler-Ross' five stages of grief.
