A common Japanese
idiom:
"sleeping early and waking up early saves you 3 mon (ancient currency)."
In ancient
Japan, a clean up fee of 3
mon per dead body found was charged.
If one wakes up early enough and unfortunately finds a dead body deposited infront of their house, they can take it to their neighbor's door, saving 3 mon.
The moral: a good sleeping pattern can be beneficial in unexpected ways.
