Is Morning Stress a Myth?

Did you know that before the invention of the lightbulb the average person slept 10 hours a night?

Damn that Edison!

I am, by nature, a night owl, like many creative types.  Living in an early-bird culture.

But I recently read that the stress hormone cortisol peaks around 7 a.m.  Is that why my blood boils when I have to rise early and leave my warm bed?   Is that an excuse to grab some more Zs?

Regardless, I was up early(ish) to great the New Year and New Decade. 

And I'm not the least bit angry about it.
