An ailment that prevents the afflicted from attending work. Over a period of time the sufferer concocts increasingly unlikely stories of obscure medical complaints that keep them from work, whilst strangely maintaining their ability to participate in physical outdoor pursuits, like say mountaineering.
When contacting their workplace to report their absense, the sufferer often greatly embelishes the details of their complaint in order to raise plausibility, whilst ironically achieving the exact opposite.
