If you're up past midnight, is it usually related to something 'explicitly' electronic - for lack of a better word - ? (Phone, television, computer, etc)
The last time I can remember being up past midnight, I was with a friend in the ER. He had heart issues. I'm a very early riser, so early to sleep too. Plus I'm over 50 and need my beauty rest....lol.
If I'm up after midnight, it's usually because my shift runs to 11:30 PM.
