> I haven't been in bed by eight since I was about six years old.

There were times when I was physically tired and had to wake up early and I went to bed at 8 o'clock. Other than that, I went to bed early on a day when I was very sad. It worked.

It is said that for a healthy life, you need to sleep early and wake up early. Like our primitive ancestors.

I read that very intelligent people sleep late. They are usually late for work because they sleep late :)
