premise: In The Wet is a novel by Nevil Shute that was first published in the United Kingdom in 1953. It contains many of the typical elements of a hearty and adventurous Shute yarn such as flying, the future, mystic states, and ordinary people doing extraordinary things.
hypothesis: In The Wet was first published in the UK more than 10,000 days ago.
reason: 10,000 days is 27.4 years and it was published 66 years ago. It's difficult because I used 10,000 days as the measurement.
