I really don't think it is a joke. I know a lot of people who do a lot of what is talked about. For the most part, a lot in the article is true.

While it may talk about a few points in a joke-like manner, it is still a pretty realistic article.

if you think it's a joke you aren't like the rest of the people (like me) who upvoted it because they were smiling and shaking their head in disbelief at how well the author quantified their behavior habits
