Joe told the First Lady he didn't feel well.

22. Night people are forced to fight circadian rhythms all the time.

It's not fun, and in my experience they can't be changed (despite the significant shaming directed at night people). But it's not that hard to be functional - I've been doing it all my life.

My normal sleep cycle is falling asleep sometime between 2 and 4 AM and waking between 10 AM and noon. I taught high school for 11 years and was in my classroom by 7 AM, fully functional 5 days a week. On weekends - and in the summers - I reverted to my body's preferred schedule. Next semester I'll be in the classroom at 7:45 AM two days a week. I won't like it - but I won't have the kinds of difficulties I observed on Thursday evening.
