Terry Pratchett was a great supporter of the move to legalise assisted dying. This was partly due to his early onset Alzheimer's Disease which was diagnosed when he was in his 50s. He described the condition as as an embuggerance.

Terry Pratchett died in 2015.

This is a conversation from the archive recorded at his home office in Wiltshire.

Terry started life writing when he was just a boy and in adult life became press officer for the nuclear power stations of the Central Electricity Board.

When the Pratchett books became hugely successful he gave up the day job and by 1996 he was the bestselling author in the UK.

In public he always wore a big hat, and in his Wiltshire studio he was an early adopter of a robot vacuum cleaner. When he wrote he worked on four computer screens simultaneously. 

Great guy!
