Convincing paragraph

The most important component in a situation of surviving alone in any location is water. The reason why is because people have claimed that an average person can live for 3-4 days without water. Without water a person with a right mind would search for some water knowing they might die if they wouldn't from dehydration. If they do look for some water and fail to succeed, that person is basically counting how many days they can survive, and maybe hope people find out how long he or she survives and put him or her in the world record book. In hatchet Brain was fortunate to land/crash in a lake so he didn't need to find or look for water, he could get water when he needed it and it was right there when he needed it. If you were in a dessert with obviously no water what is the use of any other component of surviving.
