I haven't sworn prolifically in almost 30 years ... right around the time I decided I should attempt to use the most obscure words in the dictionary. The strange thing is, I think swearing (or not) is simply a habit and that, if you want to, you can change your habits.

I should also note that there has been plenty of swearing at the places I've worked over those 30 years, but I've only found a very small percentage of it offensive, so I'd suggest that the article is reasonably accurate.
