SLEEP.....My Biggest Enemy...
SLEEP.... Its a 5 letter word that means nothing to me.... But its the one thing which I envy the most. Not many would understand what I am saying here... But that is the truth..... By definition.. Sleep is a natural state of bodily rest observed in humans and other animals. It is distinguished from quiet wakefulness by a decreased ability to react to stimuli, and it is more easily reversible than hibernation or coma . It is common to all mammals and birds, and is also seen in many reptiles , amphibians , and fish . In humans, other mammals, and a substantial majority of other animals that have been studied (such as some species of fish, birds, ants, and fruit flies ), regular sleep is essential for survival.
