For your initial post, different cultures encourage different patterns of sleep. For example, in some cultures, an afternoon nap is a normal part of the day and in others, people are expected to stay up all day. Research two cultures with different expectations for when and how sleep is expected to occur. How do these differences affect the health of the population; how do they affect productivity?
For your reply to a classmate, describe how changing the sleep pattern of either culture your classmate described might affect people’s health and happiness.
