Firstly it kills people. The book Why We Sleep claims a lost hour of sleep is bad for the heart. Heart attacks rise 5% the day after switching the clocks. There's also a spike in traffic accidents.

Thirdly, it creates an unhappy society. Judges hand out 5% longer sentences and use of the word "tired" rises 25% on Facebook.
