What is your kids bed time?

I have 5 kids ages 18, 15, 11, 9 and 7, the 3 youngre ones fo to bed at 9pm they are laying down watchikng tv at 8pm. My 15 yr old lays down at 9am and goes to bed at 10pm. I think having a routine for our kids they they become accoustomed to haelps them rest better. I have allowed them to stay up later as they had gotten older and as long as they are able to get up for school on time with out having any attitude or being overly cranky and as long as they are able to function at school and stay on task it's all good with no worries. It has worked well for us as I am an organized person to it's only expected that my kids know what I expect of them and so every thing runs smoothly. How about your self, do you have kids and are you set on bed times for them as well? How would you answer your own questions?
