Living underground for months
Though this article outlines succinctly the physical and mental difficulties faced by the 33 trapped Chilean miners, it also tends to overemphasize the worst case scenerios, none of which are likely to happen. I can state from personal experience — having spent numerous weekends underground during cave exploration trips — that though their situation is very unpleasant, I have no doubt these miners will survive. Because they have contact with the surface, and therefore a regular supply of food and information, they will simply demonstrate the limitless range of human endurance, and hold on until rescue arrives.
