M: Your website is outstanding. BarbaraWit.com is easy to navigate through and very informative. Did you have a lot to do with the development of the Website under your name?
W: Thank you for your compliment. Yes, I gave the overall creative direction for the site while at the same time closely listening to my designer's recommendations. The most interesting feature on the site is my free, interactive screen saver. This is kind of a technological novelty that we built from scratch. Unlike your standard screen saver, my screen saver updates automatically without requiring the user to download additional files. It all happens “in the background” while you are online performing other tasks. Once the user has downloaded my screen saver, I can refresh the content of the application on the fly, thereby always keeping the content current. My fans love the screen saver because they enjoy the daily excitement of finding new pictures on their desktops. Meanwhile, through my website, fitness lovers are kept well informed about new trends in the fitness world.
M: The pictures on your Website are some of the best kind I've seen. You look like a natural in front of the camera. Did being in front of a camera take a while to get used to?
W: Not really, considering that I started posing at the tender age of nine. I have always loved the camera.
M: What are some other hobbies you enjoy?
W: Besides working out in fitness clubs or gyms, I enjoy cooking, gardening, dancing and hiking the most. And,
of course, I enjoy listening to music.
M: What kind of music do you listen to?
W: I have a pretty eclectic taste. Anything from light rock to smooth jazz, from alternative to classical and, of
course，Latin beats.
M: With all the modeling and acting you do, is it hard to have a social life?

1903 - Sleep Debt
Now, let's turn to teenagers and see what effects will “sleep debt” bring to them in their studies and lives. Most people always assumed, always kind of thought that adolescents stayed up late because they liked to -- which they do -- and because there's plenty of things to do -- which there are ... Teenagers, when allowed to, sleep nearly nine and a half hours every night -- as much as young children. But unlike young children, even when teens do get their full sleep, they're still out of sync with everybody else. They have waves of sleepiness in the daytime, and then surges of energy in the evening, making them wide awake late at night. But not, scientists have discovered, for the reasons most of us assume. It is found that there's a big push from biology that makes teenagers such night owls. It comes from that mighty sleep hormone, melatonin. Melatonin is a wonderfully simple signal that turns on in the evening. So you're getting sleepy. And it turns off in the morning. So you awaken. During adolescence, melatonin isn't secreted until 1l:00 p.m., several hours later than it is in childhood. So the typical teenager doesn't even get sleepy until that melatonin surge signals the brain that it's night, no matter how early the teen goes to bed. And the melatonin doesn't shut off until nine hours later, around 8:00 a.m. But of course most high schools start around 7:30. The result is all too evident. A teenager's body may be in the classroom, but his brain is still asleep on the pillow. The student will wake up and go to school, but he can't keep his eyes open and just feels miserable. What's wrong with him? The melatonin it's still on; it's not off.
In our lab studies, the typical teenager, when monitored in a quiet environment during morning hours, will fall asleep in less than three and a half minutes. It's just like magic. It's like somebody turned on some kind of gas in the auditorium. And they all look gassed. Not gassed, of course, they're just severely sleep deprived. An adolescent, and particularly the adolescent in high school, is almost bound to get severely sleep deprived, short about two hours of sleep every school night, accumulating into what scientists call “sleep debt.” It is estimated that 85 percent of high school students are chronically sleep deprived, unable to stay fully awake throughout the school day. At least 60% of them are suffering from “sleep debt.” And it's not just falling asleep in class. There're other serious effects, like falling asleep in riding a bike, playing sports, using tools, even driving a car. The Federal Department of Transportation estimates teenage drivers cause more than half of the fatal accidents.
In addition to those straightforward effects, there are more subtle effects on their cognitive thoughts and their emotions. Scientists have discovered that teenagers, when tired or sleep-deprived, are more irritable, more prone to sadness. And their performance on intellectual tasks drops dramatically. In short, their reaction and response, alertness, judgment and concentration, all slowed down by insufficient sleep.
