Clive and Liv discuss famous predictions of the future including those by Nostradamus and journalist Simon Reeve. They are also fascinated by the story of someone who claimed to have travelled back in time from the 2030's to the early 2000's to retrieve a computer code which was causing chaos in his own time. Plus they consider how they would act if able to go back in time - would they warn people of impending disasters or just say nothing?
