As such, a "good morning" could mean "a good day's plow". </P> <P> Some languages that use the time of day in greeting have a special greeting for morning, such as the English good morning .

It may also include information activities, such as planning the day's schedule or reading a morning newspaper . The boundaries of such morning periods are by necessity idiosyncratic, but they are typically considered to have ended on reaching a state of full readiness for the day's productive activity . For some, the word morning may refer to the period immediately following waking up, irrespective of the current time of day .

The ability of a person to wake up effectively in the morning may be influenced by a gene called "Period 3". This gene comes in two forms, a "long" and a "short" variant . It seems to affect the person's preference for mornings or evenings . People who carry the long variant were over-represented as morning people, while the ones carrying the short variant were evening preference people . </P>
