The Ultimate Vampire Resource and Directory

Has anyone ever heard of the Jumping Jack Flash Hypothesis?
Their site is pretty interesting. Do you think people actually flake out because of their environment and turn into zombies?
Do you think this is how the zombie apocalypse will break out?

Quoted from the website- "Zombie-like Behavior - Hydrogen sulfide is a broad-spectrum poison but has powerful neurotoxic effects. In other words, it harms the brain, the neurology. It appears that it harms the higher functions: morality, conscience, logic, reason, language, memory. The result is that in some small percentage of the population, people just...lose it. They eat other peoples' faces, or eat their own son (happened in Uganda), etc. Cannibalism seems to be a common effect in this small percentage of the population. (Most people it simply kills outright.) So as we all breathe it in more and more, there will be more people doing simply insane things, from stripping off clothes and chasing buses to attacking and chewing on people."
