You bring up an interesting point. There's some neurolinguistic research that points to profanity being more the domain of the amygdala, the so-called "reptilian brain". This is supported by both neuroimaging and studies of patients with aphasia, which show that people with damage to brain regions governing conventional speech can still retain the capacity to swear. Another study suggests that swearing helps the utterer better withstand pain, by stimulating the fight or flight response mechanism centered there. http://harvardsciencereview.com/2014/01/23/the-science-of-swearing/ http://harvardsciencereview.com/2014/01/23/the-science-of-sw... http://www.scientificamerican.com/article/why-do-we-swear/ http://www.scientificamerican.com/article/why-do-we-swear/
