I used to have really fixed ideas about what was normal for 7 a.m. and midnight. That binary approach to waking life has been transformed and I now go about my business half awake, ready for sleep whenever the opportunity avails itself.
Crunching numbers at 3 a.m.? Sure.
Sleeping at 3 p.m.? If possible, absolutely.
Making cupcakes at 6:30 a.m., frosting them by 8? Not unusual.
Being awake at 5:30, just to be alone. Yes.
I blame artificial light, and cellphones and a whole range of things, but it certainly has opened a whole new range of options. These hours are no longer the front and back covers of a big heavy book, but rather are like beads sliding along a string, catching and refracting the light.
