How do you know if someone is a zombie?

Answer 1

The brain and/or flesh eating usually gives it away. But rotting while animated is a pretty good sign as well.

Answer 2

You can determine if someone is a zombie by looking for classic signs such as pale skin, vacant stare, clumsiness, and a lack of verbal communication and emotional responses. Additionally, if the person attempts to attack or bite others, it may indicate that they are exhibiting zombie-like behavior.
