We should have learnt this at school and not frigging algebra...
"Zombies are not mindless hunters. They are swifter and craftier than one might expect. A lone zombie can burst out of hiding and take a chunk out of you in the blink of an eye."
Never engage a zombie if you can avoid it
"Though zombies are surprisingly quick in confined spaces, they are not swift runners. Engage the zombie only when you are trapped, and escape is not an option."
Focus on the task; keep fear out of your head
"No one, no matter what their powers of description, can fully prepare you for your first encounter with a zombie. Their grotesque appearance and smell, along with the inhuman noises they emit, can induce a level of fear and terror that precludes rational response and causes one to freeze. You must not react to the zombie's appearance. Focus instead on delivering a combination of offensive and defensive strikes that will buy you enough time to escape. "
Do not allow the zombie to get a grip on you
"Once a zombie wraps you in its powerful grip, your prospects for survival are minimal. Therefore, your first priority must be deflecting away the zombie's hands. "
Seek medical attention after any encounter
"Always have trained medical personnel examine you as soon as possible after any encounter, even if no wounds are visible. The zombie virus can enter your body through the smallest opening in your skin, be it a scraped knuckle or a nicked elbow."
