After spending a few minutes in the cave, you will understand why the average life expectancy of these miners is only 40 years, and why 8 million people died in this mine over the centuries. It is an absolute nightmare: due to the lack of oxygen and toxic fumes/dust, breathing is already difficult when staying still, but climbing ladders and crawling into muddy tunnels simply make you choke.
