I came across with an informative article that the British Medical Journal reviewed research on harms arising from laughter and produced a wide-ranging list of laughing-related dangers, from asthma attacks, protrusion of abdominal hernias, jaw dislocation, and stress incontinence, cardiac and oesophageal rupture and cerebral tumours. The Oxford researchers concluded "Laughter is not purely beneficial. The harms it can cause are immediate and dose-related, the risks being highest for Homeric (uncontrollable) laughter". I suspect that we may need a repeat prescription for an anti laughter pill soon.
