In recent months, since the election of Japanese woman Prime Minister, Sanae Takaichi, the topic of sleep has again emerged. She said she only sleeps about two hours a night. However, she also told that was her personal schedule and not advocated for the rest of Japan. Except maybe, for her Cabinet.
Sleep, or the lack of sleep, has become a weapon, to make subordinates work and not sleep. Takaichi has been known to conduct meetings in the early hours of mornings.
Likewise, neighbors who use talkative voices, or energy waves to interrupt sleep and wake up people, are a kind of tyrant, who impose their will on others.
