I have experienced Brain farts when in the fallacy of multitasking because you are expected to be able to answer emails, chats and voice calls all the same time while, reading a certain law on human rights and deliberating if to fire or not fire someone.

That extent of distraction can make someone lose concentration and apt for making mistakes. So I try not to multitask as best as I can.

Brain-drain yup happens as well when all the ideas in your mind have been used up in trying to explain that that the cause of the high attrition is because of a bad manager who is a favorite. That all your logical, creative and reasoning just leaves you because you have exhausted all trying to explain and they won't budge.

Brain dead well I see these with the people who value short useless content like eating a Tide pod or news about the Kardashians or believing that Kanye is right when he said that Slavery was a choice by the African Americans.

I agree that if the effort is placed to make things better, to learn and absorb knowledge and find the truth we can be a better society but as it is the powers at be wants to dumb people down so that they can continue to rule and so they invest heavily in these viral videos, dictate what is cool and use cinema and tv to hide the truth and exert propaganda.
