It is important to note that wikpedia articles is limited to what exist in sources, and if the sources don't consider alternative perspectives than the article can't do it. The article do link to Salaryman, and from there Karoshi, which is one observed effect when people has lost their jobs, which in turn is not identical to retirement but has common aspects to it. Both Karoshi and Retired Husband Syndrome are defined as psychosomatic stress-related illness caused by the model breadwinner. (https://en.wikipedia.org/wiki/Karoshi)

It might be worth linking the two together at the bottom of the Retired Husband Syndrome article.
