Breakfast vs Brunch

I woke up around 11am just now.. Head and body aching.. Not good. God actually created day and night for a reason. Day for work and night for rest. From now on, I should get up earlier ( well, get up late once in a while is fun though, hehe ) and go to bed earlier.. I think I slept around 2am last night. My mum always says it's bad for the health, as far as strong immune system and body skin condition are concerned. Ok mum ! I'll try my best.
