Final answer:
Regular liberty, considering historical legal decisions and a typical human day, should not exceed seven hours to balance work, personal time, and sleep within a 24-hour period.
Step-by-step explanation:
The question you're asking is about the maximum number of hours that regular liberty, or time away from required duties, should not exceed. Historically, there have been many debates and laws regarding work hours. For instance, in the case of Lochner v.
New York, the New York law setting a maximum ten-hour workday was struck down. When considering the constraints of personal liberty balanced with the rights of individuals to contract freely, this case upheld the notion that limiting work hours could infringe on liberty.
However, considering both the historical context and the practical considerations of a human day, the answer is that regular liberty should not exceed seven hours, assuming a standard of eight hours for sleep and the remainder for work and personal time, according to a typical time constraint of 24 hours in a day.
