Remember, if Ninja's can't catch you while you're on fire, than neither can zombies.
In a post - apocalyptic zombie world, you can be one of three things: one is a zombie, one is dead, and one is alvie and not a zombie.
If you're a zombie, no worries, you have no will. If you're dead, you can't worry.
If you're alive, you can be in one of two places: a safe(well defended and supplied)one, or a dangerous one.
If you're in a safe place, don't worry, but check every so often to tell its safe.
If it's dangerous, it can be for one of two reasons: because there's zombies, or for another reason.
If it's zombies, why are you not fighting right now? Regardless, you can be one of two things: wounded or not.
If you're not wounded, don't worry (well, maybe a little if there's zombies)
If you are wounded, it can be for one of two reasons: caused by a zombie (clarification: caused by a zombie causing a cut or laceration using nails, bone fragments, teeth, or any other sharp object, or one that has come into contact with some form of bodily fluid.) or not caused by a zombie (including zombies pushing debris onto you,any other lacerations, or friendly fire {remember, the most accurate fire is always friendly}). See your medic.
If it was caused by a zombie or unknown, he will put two rounds in your head.
If it wasn't caused by a zombie for sure, he will ask if it's slight or severe.
If it's slight, don't worry, but be sure to shield it from bodily fluids. Your medic will supply bandages, but you have to apply them yourself as he fights.
If it's severe, it is one of three things: a broken bone,a laceration, or another severe injury (muscle tears, sprains or some form of mobility - damaging injury)
If it's a broken bone, don't worry, your medic will also give you a straight object with your bandages, but you still have to apply them yourself as he fights.
If it's anything else, you're dead, so you can't worry.
In these situations, no survivor will ever be worried. Shot up, a zombie, dead, loopy on painkillers, and cursing the medic as he attempts to save you, but never worried.
