On my goodness! that poor third man... who ate sand...
Too bad he hadn't a clue that the oasis lake was just over the next hill... Poor fellow... must have been quite insane and mindless to eat sand when what he needed was water... may he rest in peace...
Amazing how the sick and the blind hold to their debilitative ailments so confidently and difinitively... and preach and defend their ailments with all their Being... Perhaps the third man (being quite retarded) should have visited a couple of shrinks, and gone to church, before taking his silly walk into the desert...
