Your cavilier comment about "dying in the woods" smacks of machoism. Am I to read it that you feel a reasonable regard for safety is whimpy? I think it is understood that all of us who backpack have, by virture of participating in the activity, accept a certain amount of unavoidable risk. Reducing that risk where you can is a no-brainer. Hypothermia is a reality and one of the leading causes of death in the wilderness - and your choice of equipment does make a difference.
