Randy Pausch, a warm, humorous and devoted university professor, was diagnosed with pancreatic cancer, cancer with the highest mortality, at the age of 46. In August 2007, he was told that the cancer hand transferred and that he might still have 3-6 months to live. In September in the same year, Professor Pausch made a speech at the invitation of his university, which made the audiences laugh and some of them shed tears. According to New York Times, at least 10 million people have watched the speech online.
