Is it copy and paste, or is it research? I see no one else bringing research and particularly this research to steem. It is not good science to state how one feels about the material, however it is good otherwise. I tend to focus on the science in my main blogs, but maybe I shouldn't and I appreciate your question (you ask a very good first question). I hope there are certain tags within steem that become emotionless bastions of scientific discussion, however I also understand the nature of this particular post is science including emotion which does confuse the matter.
As to your other question, I am not fluent enough in psychology research to know. I am not an expert. My opinion is that while this article does not apply to your singleness (or anyone else'), one cannot separate the study of singleness from the study of relationships. Mr Wang, you are not a statistic in this moment, and your relationships can all improve if you want them to more than you want to be too busy. I would say that some elements of the list near the end of my blog post still may help you improve any relationship you have, whether romantic or not.
Try and let us know, if you are willing.
