It is no secret around here that I am a huge Terry Prachett fan. I have -- I hope -- managed to spread my fondness for this writer amongst my various and sundry Internet friends.
So, the news that Mr Prachett had been diagnosed with early-onset Alzheimer's disease was a terrible, terrible shock.
By way of my friend Peter, we have a link to an article written by Terry Pratchett in which he describes his on-going experience with the disease.
It is a compelling read.
