En del folk har för lite att göra... Här är en studie på svärdslukning och dess bieffekter.
De kommer fram till något sånt som att det problem med halsen är vanligt under inlärningsfasen, och att man som svärdslukare tar en finansiell och fysisk risk... (Det kom verkligen som en chock.. :

Sword swallowing and its side effects

British Medical Journal 2006 Dec 23;333(7582):1285-7
OBJECTIVE: To evaluate information on the practice and associated ill effects of sword swallowing. DESIGN: Letters sent to sword swallowers requesting information on technique and complications. SETTING: Membership lists of the Sword Swallowers' Association International. PARTICIPANTS: 110 sword swallowers from 16 countries. RESULTS: We had information from 46 sword swallowers. Major complications are more likely when the swallower is distracted or swallows multiple or unusual swords or when previous injury is present. Perforations mainly involve the oesophagus and usually have a good prognosis. Sore throats are common, particularly while the skill is being learnt or when performances are too frequent. Major gastrointestinal bleeding sometimes occurs, and occasional chest pains tend to be treated without medical advice. Sword swallowers without healthcare coverage expose themselves to financial as well as physical risk. CONCLUSIONS: Sword swallowers run a higher risk of injury when they are distracted or adding embellishments to their performance, but injured performers have a better prognosis than patients who suffer iatrogenic perforation.Här är fulltextversionen för de som är speciellt intresserade..:
