That is the description occupational therapist Kim Evans gives to motor neurone disease, which she is selling on eBay.
"Are you interested in extreme sports? If so there is a unique, once in a lifetime offer waiting for you!" writes Ms Evans, a mother of two of Porthcawl, south Wales, who was diagnosed with the progressive, degenerative disease in September.
At the time of writing, there have been 26 bids, the highest for £100 and Ms Evans said the proceeds will go to the Motor Neurone Disease Association.
"It started off with me getting fed up and cheesed off with MND and I wondered what people do with things they no longer want ... and I thought it would be funny [to put it on eBay]," she told the Press Association. "I thought that if I could make money for charity ... and raise awareness ... that would be fantastic."
eBay, of course, has been no stranger to having unusual items and services offered on its pages. In 2003, a man from Sevenoaks, Kent, put one of his kidneys up for sale but eBay later ruled that organs could not be sold on the site.
A year later a 19-year-old student from south London offered her virginity on eBay. She was stopped from using eBay and set up her own auction site and was later said to have received £8,000 from a businessman, according to the News of the World. Also in 2004, a woman in Florida made more than £15,000 from selling a 10-year-old cheese sandwich "showing the image of the Virgin Mary" and in the UK someone paid £60 for a bottle of Lake District air.
A British man also received around £10 for his "soul" in 2004, promising to send the buyer an ownership document.
A glance at eBay today shows that more human souls are being offered on the auction site, casting the site as an unlikely kind of Mephistopheles. One 17-year-old student from the Yorkshire Dales whose soul is currently for sale, says that it is "uncontaminated" and has "lots of brownie points", but warns it also "comes without a conscience".
News blog would, however, remind would-be vendors of souls of the unhappy experience of Bart in the episode in the Simpson's where he sells Millhouse his soul for $5.
Finally, if you are not interested in souls, you might consider buying the tiny town of Bridgeville, in northern California, which is apparently going on sale later today.
