I still get up early, despite the fact I have the luxury of being able to sleep in a little later. I got up at 5 AM for 30 years... I still get up by 5:30 most week days, although sometimes I sleep in until 6-6:30. Any later than that, it feels wrong.
On the weekends, I usually get up early, but let myself go back to sleep until 7-8. If I don't sleep, my husband and I usually watch the news in bed and sort of loll around until 8. Well, at this time of year. In the summer I tend to be out of bed at the crack of dawn.
I went to bed at 9-10 for years. I don't think it's weird. I do stay up later now, but there are nights when I get in bed at 8 and watch TV for awhile or read.
The older I get, the more I appreciate sleep!
