The ability to build a fire for warmth in an emergency is one of the most basic survival skills you can learn. Like most people, chances are good you'll have access to matches or a lighter during an emergency, so even in the case of total non-preparedness you can build a fire. However, to increase your odds of survival, you may want to carry around a magnifying glass just in case matches aren't readily available.
