Why do we sleep so much?

I dont know what about you, but I L-O-V-E  to sleep. It is so pleasant… When I am in holidays I always tell my friends I will hibernate lol! One day I slept for 12 hours( well, I was in holidays)

What about you? Do you enjoy sleeping very much?  How many hours do you like to sleep?

i cant  seelp  when  we  are hungry

eating just before sleeping is really a disaster for your body and brain. try to ignore your hunger or just eat some light food

I fall asleep soon when i'm happy

I fall asleep soon when i'm in a blue moon

and they all disapear when i wake up

let's my reason

i won Whitney, one day I slept for 14 hours :P

I like to sleep 8 hours a day , but i usually sleep only 7 hours a day. in holiday i sleep 9 hours .i think ,sleeping too much is not useful

I used to sleep for really long periods of time but recently I haven’t been able to even doze off as easily as I used to =/

the more i sleep, the more i want to sleep :P i dont remember what was my record but once when i was really younger.. i woke up around 2 pm and my mom asked me if i was feeling ok coz she thought i was sick.. well i just dont remember at what time i went sleep :P

when i have class i dont sleep more than 6 hours and when i'm in an exam period i sleep even more less.. but more than 3 hours! on weekends i sleep for probably 10 hours :P the same for holidays.. but it can vary! i hate when i wake up in a weekend or a holiday.. look the clock and see it's 6 am ¬¬ hehehe

At least 9 hours everyday.

owh my god, i wish if i can sleep more than 5 hours a day !!!

honestly i sleep max 5 hours a day, usually less... i know it is not healthy but i cant sleep more, i dont know why !!!, and if i sleep more, i will be lazy and feel of pain and headache rest  of the day

wow, 12 is toooooooooooooo much
