So the deeper stages of sleep are really those times of quiescence, you're really restoring your body and we have a few different stages of sleep.

So, sleep deprivation, and sometimes an insomnia, which is a little bit of a different form, but just getting a lack of sleep, can lead to a number of different decrements.

Workplace accidents with people who are sleep deprived or people who work shifts and they don't get the right amount of sleep during the day or at night.

So there's a few different ways that we treat insomnia. The first thing that we always do is we look at the cause.

We try not using medications initially, and we use something called behavioral therapy for insomnia. This changes behaviors people do in bed, none of the tossing and turning.

So when it comes to circadian rhythms, it's a clock that's basically programmed in our body. So if you think back to times when people lived on farms and we didn't have electricity.

We haven't really - it's harder for us to set those rhythms. So it's really important to keep a steady bedtime and wake time to really lock in those rhythms.

Now circadian rhythms become very interesting and problematic for patients because when you become a teenager, your rhythms actually tend to naturally shift.

And you cycle throughout so that you do about five to six cycles throughout the night. And we spend more time in REM later on in the night than we do earlier on.

So people only focus on getting the really deep sleep, but in reality, we spend almost 60% of the night in the stage two sleep.

Really if it's an hour or two after you've fallen asleep because you're in such a deep sleep at that point.

But then had come the voice that said, Come on, you little freak, wherever the hell you are, whatever the hell you are, let’s get this done with.

It's hard to imagine, seeing all of us breathing yet one day each of us shall be gone, leaving memories.

She lit my soul and inhaled deeplyFlicking my ashes occasionally.

Nicole Richie invited me to her birthday party, and it was at Michael Jackson's Neverland!

Obamacare would never have passed without decades of massive immigration from the Third World. Liberals didn't change any minds - they changed the voters.

A boycott is, inherently, a blunt instrument. It is an imperfect weapon, a carpet bomb, when all involved would prefer a surgical strike.

But I was the most unashamed lone parent you were ever going to meet.

Lil had always believed that a person's duty was to make the best of the hand they were dealt. No use wondering what might have been, she used to say, all that matters is what is.

The process of composition, messing around with paragraphs and trying to make really good prose, is hardwired into my personality.

I've been called the first Asian legislator in our Nevada State Assembly.
