I envy your situation. At 4:00 I usually still have a couple of hours to go at work (I hope I'm still alive when I retire, but either way I won't miss working, it's all good at that point).

I retired when I was 55 ... it has been perfect! :)
Had a busy morning:
We went to Costco at 0900 then to Ye Olde Pancake House, for breakfast.
I readjusted the latches on my electronic locking, pickup tonneau cover, when we returned home ... :)
I'm about ready for a nap. :)
