I think it's possible if sweelee holds a 50% storewide sale everyday and everyone will be like queueing up outside the factory. no mood to sleep. LOOL.
Don't try to quit sleeping. I tried during my p6 holidays. Slept from 6 am to 9 am for a week. Played comp the rest of the time. Caught a high fever at the end of it.
Don't quit sleeping. It's important for your body so you can recharge yourself. Your organs can rest and cells can be repaired. Usually 7 - 8 hours of sleep is good for you.
Oh! Sleeping is early is good too, around 10 pm. I should be saying this to myself.
Technically you don't have to sleep. Even scientists don't know WHY we need sleep just that if we don't sleep there are certain negative emotional effects on our mind. It's not exactly to regain "energy" because we get energy from eating food, not sleeping. That's why there are people in the world who actually don't need sleep cuz their brains have another way of dealing with the buildup of acids and fatigue. Which is quite cool given that they can maximize their everyday. I think they can sleep if they want to though.
