usually by the end of the day, we are all exhausted..due to our busy lives, etc. our body needs a break! and sleep allows our body to rest. everything that is alive needs sleep to survive, even animals! sleept is also important for u to rest your brain too hehe...when your body doesnt have enough hours to rest and sleep, you may feel tired or cranky, or unable to think clearly. getting enough sleep also keeps you healthy, in a way! .

why sleep? - We have to sleep minimum 4 hours daily.
We have to sleep because it is essential to maintaining normal levels of cognitive skills such as speech, memory, innovative and flexible thinking. In other words, sleep plays a significant role in brain development.
