Joe's World War Z review 2

In World War Z so far, the main character is talking about how the zombie virus started. The virus started with scientists trying to find a cure for alzheimers. But somehow, it went wrong. Instead of curing alzheimers, it started the function to the brains of the dead. It restarted the brain, but did not bring back any memories or feeling. So all the zombie craves is human flesh and food. As more people got bitten, it started the apocalypse.
