The mine tour was very interesting. We got to see how the minerals are mined, processed and what the finished product is. In the Potosi mines, they are all collective, which means that each miner works for himself. Actually, groups of miners work together as a team; they each have their own area of the mine. There are approximately 15,000 people working in the mines, the youngest is about 8 (which is illegal, the age limit is 18) and the oldest is about 68 (which is rare, many die after 10 or more years from black lung).
We were down inside for about 2 hours, breathing dust and stuck in small hot spaces. It was horrible. I cant believe so many people spend 8-10 hours a day in that (6 days a week)!! I really have a new respect for the miners. After the tour, we went outside and we got to set off dynamite. It was pretty cool. With a wick of about a foot, you have about 4 minutes before the dynamite goes off.
Now we are back in the town, walking around, waiting for our overnight bus which will take us to Cochabamba, which is where we are going to do a month of volunteering.
