World's best preserved mummy discovers in China * Still has hair, teeth at 2,100 years old

Better known as the Lady of Dai – scientists consider her the best-preserved mummy ever discovered.

Her skin is soft to the touch, her arms and legs are bendy, her internal organs are intact, and she still has her own Type-A blood, hair and eyelashes.

Xin Zhui lived during the Han dynasty (206 BCE – 220 AD) and was the wife of the Marquis of Dai.

Her tomb was discovered inside the Mawangdui hill in Changsha, Hunan, China, in 1971 when workers were digging an air raid shelter, reports The Sun.

According to an autopsy, Xin Zhui was overweight, suffered from back pain, high blood pressure, clogged arteries, liver disease, gallstones, diabetes and had a severely damaged heart.

It is believed she passed away following a heart attack at the age of 50 – probably after over-indulging a fair bit – although forensic archaeologists managed to deduce that Xin Zhui’s last meal was most likely a serving of melons.

In her tomb, which was buried 40 feet underground, she had a wardrobe containing 100 silk garments, 182 pieces of expensive lacquerware, makeup and toiletries.

She also had 162 carved wooden figurines representing servants in her tomb.

According to records, her incredibly preserved body was swaddled in 20 layers of silk, immersed in a mildly acidic liquid and sealed within four coffins.

This vault of coffins was then packed with 5 tons of charcoal and sealed with clay.

The tomb was made watertight and airtight so bacteria wouldn’t be able to thrive — but it remains a scientific mystery just how the body was preserved so well.
