ZOMBIE INVASION

I would take a long stress relief vacation. Blowing up Zombies and cutting them down with my various melee weapons. In fact that guy down at the mall that I always wanted to hurt would be free game if he became a zombie. Asshole...moving on though if a zombie was real it would be forced to go by the same laws of physics we do. Meaning no fast and strong zombies. In fact the fastest and strongest would be the most recently turned. With the zombies who were infected for a while would rot away to a point where they could no longer stand because they would have no more muscles on their legs.

Also old people zombies would be screwed.

Takes muscle to move and bone to give you form. Zombies would be screwed due to the rotting part of their lore. Less muscle = less strength and to an extent less speed as you no longer can throw your arms and legs with the same force. But a 65+ year old turning zombie would suck they would be unable to so anything.

Also a suit of full plate would become the ultimate armor since fists already have a hard time going through steel. I would imagine a rotting fist would merely break on it. Hell some good leather would do the trick since it's light enough to pack on even in soft spots. Or just get chain mail since that would be more form fitting and cover you completely.

However one thing that would work only so mildly is a modern army. A bullet would go right through the suckers and probably not stop them unless it took off a leg. What's worse is that modern armor would suck nuts against them since it only covers so much and leaves a lot open and easy to scratch.

In a nutshell those who are not too shy to get medieval on their ass would be fine. Just avoid weapons that pierce since it would be more effective to bludgeon or slash.
