1. How many hours do you usully sleep at night?

I usually sleep 7 hours at night.

2. What time do you go to bed?

I usually go to bed at 12 o'clock

3. Do you go to bed at the same time everyday?

No I don't. Because the amount of homeworks is different in each day 

4. Do you think sleep is important?

Of course. Sleeping makes our brain feel comfortable after 1 hard-working day

5. Should older people sleep more than children?

May be if they have time. Because people from 20 - 60 are busier than children so they don't have enough time to sleep.
