People usually die for sheer stupidity, like reaching out a previously locked door to grab some unimportant thingy on the ground only to be bitten by the zombie hidden behind said door. Usually the survivors all die because of another survivors stupiduty/greed/fear/laziness. The count usually starts off around a dozen at the most and by the end there is usually only one or a few.
My remedy: just kill everyone around you leaving only yourself is a sure way to survive.
That brings up the wonderful paradox of you now being a stupid/greedy/fearful/lazy douchebag. You were stupid for killing off your friends and fellow survivors, greedy for wanting the whole "living" thing exclusive to you, afraid of dying, and didn't want to expend the effort of surviving as a group. You will die in 5...4...3...2...ZOMBIE!
Seriously, the zombie apocalypse scenario shows the monster in much the same way that the film Aliens did. The actual villain is humanity's distrust of one another and greed, and the zombies are merely a catalyst that demonstrates this. Romero's films were a visionary social commentary more than anything else. Therefore, as a rule, zombies must have some tongue-in-cheek humor about pop culture or where society is heading when they appear.
