We excluded cases in which injury was related to swallowing items other than swords, such as glass, neon tubes, spear guns, or jack hammers.
Some let the sword fall abruptly, a manoeuvre known as "the drop," controlling the fall of the sword with the muscles of the pharynx, and some invite members of the audience to move the sword.
Shivers. I don't think I'll take that up as a hobby.
On a more serious note, there was a comment on the paper which I thought was very interesting for medical science:
Having recently undergone an extremely uncomfortable endoscopic exploration of my own oesophagus and stomach I have learned that I have a small hiatus hernia. This perhaps explains why I still have ‘the worst’ acid reflux despite my religious use of esomeprazole 40mg and an array of ‘lifestyle’ measures. I read the sword- swallowing article with great interest especially the discussion on how sword swallowers must train themselves to voluntarily exert control over normally involuntarily controlled sphincters. I wonder if sword swallowers could teach GORD (gastrooesophageal reflux disease) sufferers to control their lower oesophageal sphincter thereby giving themselves relief of sometimes very resistant symptoms?
Very interesting indeed.
