"The Zombie Invasion scenario has been a common trope in American popular culture for
decades. In one version, the outbreak begins with a mutant virus introduced to a small
population of humans. The virus kills those whom it infects, and after a period of time, causes
them to rise from the dead with an insatiable hunger for human flesh. Decaying mockeries of
human life, these walking undead are insensible to cold, heat, fatigue, or fear. Mindless, they
possess only the most basic instinct to feed upon the living."

Considering my recent sleeping problems, I kinda feel like a zombie myself, lol.
