  Urgent treatment for neoplasm consists of (1) cautious use of intravenous diuretics and (2) mediastinal irradiation, starting within 24 hours, with a treatment plan designed to give a high daily dose of radiation but a short total course of therapy to rapidly shrink the local tumor. Intensive radiation therapy combined with chemotherapy will palliate the process in up to 90% of patients. In patients with a subacute presentation, radiation therapy alone usually suffices.

  What is the good life? What is the good man? The good woman? What is the good society and what is my relation to it? What are my obligations to society? What is best for my children? What is justice? Truth? Virtue? What is my relation to nature, to death, to aging, to pain, to illness? How can I live a zestful, enjoyable, meaningful life? What is my responsibility to my brothers? Who are my brothers? What shall I be loyal to? What must I be ready to die for?—Abraham Maslow
  
  Please reflect and respond to the following questions: What is the good life to you? Who are your brothers (i.e., your people)? What should you be loyal to?
  
  I appreciate your honest reflections (in advance).
