You Can’t Live Forever
What Chin Shi Huang was most interested in was immortality through a “Life Elixir”. However, his quest to live forever backfired. His efforts to find a Life Elixir not only failed, but also did the opposite of what China’s First Emperor wanted, and shortened his life. In pursuit of immortality, Chin Shi Huang solicited advice from numerous philosophers, alchemists, opportunists, sketchy characters, and outright charlatans. One adviser gave him mercury pills, which he claimed were a life-prolonging intermediate step in his research for immortality drugs. Using them every day should tidy Chin Shi Huang over until the Life Elixir was ready.
The First Emperor swallowed mercury every day, gradually poisoned himself, and grew insane. He became a recluse, concealed himself from all but his closest courtiers, and spent much of his time listening to songs about “Pure Beings”. Many of Chin Shi Huang’s nuttier decisions, such as the burial of scholars and burning of books, were probably caused by the mercury pills. Rather than prolong his life, the pills gave him a nasty dose of mercury poisoning. It made the emperor literally crazy, and finished him off at the relatively young age of 49.
