mockturtle - You are so correct, plus, if put in the same situation, half of us might ultimately come to the conclusion that doing nothing was no longer an option, and that there was nothing to lose by trying to walk for help.
Case in point, three friends of our family were white water rafting on the Cheat River. It was in the fall, and all of the commercial rafters had finished for the day.
Their raft overturned. Then, in attempting to capture the raft, one person fell down a ravine and severely smashed his foot on the rocks below.
His sister and the third person in the raft walked out not knowing exactly where they were headed. They found help, and a helicopter rescued the guy with smashed foot that was left behind. They said that the helicopter arrived probably an hour or so before he would have become deceased.
You just never know.
