VARIATION IN SLEEP PATTERNS OF CERTAIN INDIVIDUALS HAS RENDERED THE DEFINATION OF SLEEP THAT MAY BE GENERALLY REGARDED AS ENOUGH SLEEP FOR CERTAIN INDIVIDUALS QUESTIONABLE.

Sleep as involuntary condition that sets our internal body organs and the whole body at rest with its function at less than half its normal function, while at rest has remained a contraversial condition in which a living organism is at rest, rather than inactive, or dormant that has not been defined as a reflex action, a form of sense, or a temporary condition in which a living organism, or body seems not to exist. Less sleep, or much of it has been both regarded as abnormal conditions that requires medical attention. Except for the condition in which sleep may be regarded as enough.
However, variation in the sleep patterns of certain individuals, due to different activities and perhaps behavior,specially at night hours has rendered that which may be generally regarded as enough sleep questionable. In other words less sleep, or much sleep may also be enough sleep for certain individuals.
