Old Man and the Sea - Did Santiago Wake Up?

When i read the vastly disappointing ending of this story. The very first thing I wondered after Santiago went to sleep is whether or not he died. I mean the story never really says. It just states that he went to sleep. It sort of leaves the question of whether or not the weathered and tired old man wakes up. In my own opinion I do not think he wakes up, or in other words I think Santiago dies that night. Its pretty obvious in my own opinion. Basically the whole book was a sort of symbol for life. Now, the fish is the easiest one to compare to live, fighting and fighting but eventually dieing. I think the fish was also supposed to represent Santiago's own life of high and low points. That makes it very obvious that when Hemingway had the fish fail to reach the shore intact. That meant Santiago will fail to make it as well. Aside from all the reading to in to it stuff there is also the medical part. Santiago had been cramped up in a boat at sea for several days. The whole time exerting himself furiously and trying to reel in the fish. Not to mention that he did not get very much fresh water or even food in general having only a few fish in a fair amount of time. As people get older their bodies begin to become frail. Thats the reason why old people move slow and have to be really careful when they exert themselves not to over do it. Why hundreds of people die from heart attacks every year while shoveling the snow from their driveway. Much less being in a small boat and fighting a thousand pound animal for days on end. It only makes sense that when Santiago went to bed with Manolin that night he did not wake up the following morning. There is also the spiritual side to it. Catching that fish was sort of a culmination of his whole life. The legendary fish people will talk about for decades to come. What would be a better time to go then while he was on top with the largest catch probably ever. Much less in the small town he had lived in.
