That's because dear @StarSong our bodies know there's less time left and need to experience ourselves awake. Before it's too late.Like several others here, I was up before 6.
I was one of those people who always slept like the dead, but that's far in my past now. One of the terrible ironies of age that many of us suffer: now that our schedules permit us to sleep late our bodies refuse to cooperate. So frustrating.
Now get up and start percolating!
