You may not be aware (not like it’s news or anything) but The Hobbit: The Desolation of Smaug releases today and, in true JSTOR nerd fashion, I got myself to the archive searching “hobbit” AND “tolkien” and again, I was not disappointed.
The British Medical Journal DIAGNOSES GOLLUM (this is a real article, I swear on Legolas himself)
"Several differential diagnoses need to be considered,and we should exclude organic causes for his symptoms. A space occupying lesion such as a brain tumour is unlikely as his symptoms are long standing.Gollum’s diet is extremely limited, consisting only of raw fish. Vitamin B-12 deficiency may cause irritability, delusions, and paranoia. His reduced appetite and loss of hair and weight may be associated with iron deficiency anaemia. He is hypervigilant and does not seem to need much sleep. This, accompanied by his bulging eyes and weight loss, suggests hyper-thyroidism. Gollum’s dislike of sunlight may be due to the photosensitivity of porphyria. Attacks may be inducedby starvation and accompanied by paranoid psychosis."
This article is amazing and, since BMJ recently joined the Register & Read program, you can simply create a MyJSTOR account to read it (and many others!) for free online.
