Terry Pratchett's death announced perfectly on twitter 

Terry Pratchett spoke candidly about facing his own death after he was diagnosed with Alzheimer’s.

He became a vocal supporter of assisted suicide — or assisted dying as he felt it should be called — and used his position as one of Britain’s most respected authors to argue eloquently for it.

Pratchett, the British author whose fantasy novels sold in their tens of millions worldwide, died of a form of Alzheimer’s disease aged 66.
