Morganitis is incurable, once properly infected.
I'd been incubating the disease since the mid 70s, but it erupted, seriously, in 2012 when I bought Aldermog. It calmed down for a couple of years, but in late 2014 I had a serious relapse and changed Aldermog the Roadster to Tarka the Plus 8. Since the infection has been broadly controlled, but SWMBO is worried that the new Morgans, due to be revealed at Geneva, could cause a major breakout.
