Mining is brutal work. In the past, miners were expected to work long hours in dangerous conditions. Without proper ventilation, the heat can also be a burden. As seen in the pictures below, the heat and sweat from mining must have been so unbearable that the men actually stripped completely naked while they did their work. In my opinion, being naked around a bunch of rocks and dangerous equipment is dumb but it clearly seemed like a good idea at the time.

What do you guys think? Would you be comfortable being naked while hauling a mining cart up a track?
