35. Sleep Deprivation
You’d be surprised how much sleep has a role in how we operate as human beings. If you ever want to know what it’s like to get to some crazy levels of mental instability, try staying up without napping or anything of the sort for one week. What you will find is that you’ll begin having several major mental issues.
See, sleep allows us to heal and it also allows our brains to not so much shut down but go into a rest mode like us. This is critical to allowing you to function properly. Could a real zombie apocalypse happen with a bunch of people who need sleep? It is not exactly the most obvious thing. However, if you begin to have problems making out something real versus something fake, this could lead you to do some horrific things.
