Early bird or night owl?

I'm a night owl by nature but after years of getting up before sunrise with Annie, I lived the life of an early bird. Now that she's been gone for a two years :(  I'm slowly going back to being more productive at night. 

When I'm babysitting the labs, they get up very early (5:00am) but right after breakfast we all go back to bed. So I live the life of a hybrid getting up early and going to bed late, which means I don't sleep a lot. I've never been one to sleep for a solid eight hours and wonder how people do that!  Maybe that should be a goal I have for this year. So are you a night owl or early bird?
