This article answers the question of why sarcasm is hard to detect in texting and email conversations. It depends on things like context of the person like the relationship you have with the person you are using sarcasm with. Also, with texting, you can't convey your emotions with facial expressions like you do in face-to-face conversation. Emojis help a little bit with that, but it isn't the same as a face-to-face interaction.

This article discusses the use of grammar in vocal conversation vs written. They analyzed the use of "are" and "is" properly and stated that it applied to written language, but doesn't really apply to spoken conversation. This is because in the middle of a conversation, we don't have the time to set up everything to be grammatically correct every time. The brain formulates the simplest and quickest response to continue the conversation.

Over the years, we have found that our words come from different parts of the brain. In addition the part of the brain which we use to formulate thoughts into sentences, we also use the part of the brain that deals with emotion when we swear. Researchers discovered that patients with neurodegenerative diseases like a stroke, were still able to swear. Studying patients with Tourette syndrome have also proved that swearing uses many areas of the brain. Since swearing involves the emotional part of the brain, we know that profanity is used to express intense emotions.

Richard Stephens and his colleagues from Keele University found that swearing makes people more able to tolerate pain. His study involved participants sticking their hands in ice cold water and seeing how long they could hold their hand inside. They found the participants who swore, could hold their hands in twice as long than the ones who said neutral words.
