If you believe in Murphy’s Law (“anything that can possibly go wrong, will”), then you definitely want to look into camping first aid kits before going on a camping trip.  If you have camping first aid kits available, then you are ready for emergencies and they won’t happen because then Murphy’s Law would not work.  Take a deep breath and think about it.  Think how often it doesn’t rain when you remember to carry your umbrella, and how often it DOES rain when you leave your umbrella at home.  Same principle applies.
