There were lot's of cyclists in DV last week. I was one of them, witnessed some of the search activtities and had heard they were looking for a cyclist that wandered away from camp. According to the article, the guy was experiencing difficulty of some sort in the days before he wandered off. If anything, it suggests to me not to take such symptoms lightly. It'll be interesting to find out what he did succumb to. The killers in DV are exposure/heat and dehydration but it sounds like he probably died from some health issue. I've spent a fair amount of time out in the desert and the last thing I worry about are snakes or scorpions.
