Another quote from Keys (1948):
"Severe caloric inadequacy produces profound changes in the personality and the subjective state. Externally,
the major characteristics are apathy, depression and introversion. Social contacts are avoided and sex interest declines sharply. Psychiatric methods reveal, besides the depression, a well defined rise in the tendencies to hypochondriasis and hysteria."
I don't have any kind of grand thesis here. Mostly I'm processing things aloud. But this backdrop definitely affects how I'm reading the news, and when I see conversations about this online.
