Natural born nightowl here, finally returning to my natural nightowl state since I retired. (Two hours ahead of you guys, here in the Mountain Time Zone.)
It's just about 6:04 AM here I guess the posting time shown will be about 4AM your time.
Somewhere on this board is a histogram graph of your posting activity versus time of day, but for some reason I can't figure out how I got to that. I guess my browser (IE) needs updating, but I hate updates.
I've been a nightowl since birth. I used to drive my mother nuts because as a baby I'd be up all night and sleep all day. She'd visit her friends during the day and I'd be conked out, and they'd all say what a good baby I was. At least thats what she told me.
I had graveyards twice in my life, once as an overnight cab driver, once as a security guard, and except for normal daytime noises causing somewhat restless sleep, I seemd to fit into that nocturnal pattern quite well.
I suppose it's part of the natural variation in the gene pool --who knows whether someday natural-born nightowls will have a survival advantage and all those "dawn-to-dusk" types will die off at the crack of dawn.
