Lady Dai. The body of Xin Zhui or Lady Dai, arguably the most perfectly preserved corpse ever found, was discovered near the Chinese city of Changsha in 1971. Buried securely with over 1,000 perfectly preserved artifacts, Lady Dai, wife to Lord Dai of the Han imperial fiefdom of Dai, was a privileged member of society. Among the many things found in her grave were fine lacquer dinnerware, exotic food, and fine fabric that surrounded her body.
Lady Dai is so well-preserved that scientists were able to bend her arms and extremities; melon seeds and other remains of her last meal were found in her well-preserved stomach; her skin was still supple; and her hair was intact. Most amazing of all, her type A blood still ran red in her veins, and her internal organs were all intact!
Even more amazing was to what extent scientists were able to trace her health problems! They found she suffered from parasites, had lower back pain and was terribly overweight at the time of her death. She had clogged arteries and a very damaged heart.
Scientists are still baffled as to what preserved the body of Lady Dai. Some say it may have been a mysterious liquid in which the body was immersed, traces of which were still found when her body was discovered.
