How much sleep did/do you get when you were around 13?

Around 6-9 hours, usually 8, I'd say.  I stayed up late messing around with the computer, writing, or doing homework.  Our school gave out a tremendous amount of school work.  On the weekends, I'd get less sleep.  I liked spending the entire day doing what I wanted, so I didn't waist much time on sleep. =)

6 hours.

Not enough -_-
weekdays, i would sleep from 1, to 6 in the mornign and be fine, and then on the weekedens i would sleep from 4 to 10 and be fine. But now it seems like no matter how much i sleep, i'm still tired. So.... Prettty much for me, when i was 13, sleep was kinda unlimitted, but when i turned 14, every minute counts X/

Probably about 8 or 9 hrs. By the time I was 17 I would work till 1am get home at 2am and sleep till 2 or 3 pm.

I got 8 hours usually. Less on weekends because I had to work for my father. He owned a construction company. Work started at 7 am Saturday and Sunday. Then back to school on Monday. :(

Usually about 9 hours on a school night and 10 at the weekends.Back then i was a tomboy and always busy at something, so i ended up being way tired and having to go to bed pretty early lol.

If no school, about 21 hours,
