This article is rubbish!
Statements like "The term is often used inaccurately to describe an energetic person", and "Japan is often portrayed as having a workaholic culture" have no basis in fact, or relevance. "Workaholic" is just a colloquial/slang term and should not be treated as a medical entry. The only relevance of an article would be regarding the term's entymology, which would be better placed in a deictionary. I nominate this article for deletion.
