He Consumed Mercury
We are talking about none other than liquid! Qin Shi Huang was of the belief that this radioactive element was going to help him retain his youth. This is why he was always around it and even ingested the liquid. Upon the completion of his mausoleum, there were rivers of it flowing through the space.
His Early Demise
There is no doubt in our mind that his propensity for mercury had something to do with his premature death at only 49 years old. On top of that, it made his resting place very radioactive. As a matter of fact, the tomb is still sealed and off-limits to everyone to this day.
