I am a terrible sleeper. I got up very early for work, for decades, and every minute counted in my quest to get out the door. When I retired I liked nothing more than to sit at the table in the morning reading or whatever, while drinking my lattes and petting my cat. I wake up multiple times almost every night. I probably usually get up by 7:30or so, with the help of my alarm clock, but I could easily sleep much later on nights when I’m awake for hours during the night.
