I read an article earlier today about sleep scheduling in work life and at the end of the article (serious newspaper, btw) was this study linked you can fill out and they send you a PDF with your result and tips how to move your inner biological clock in a certain direction.

My results were pretty accurate I feel, they recommended me to get up to 30 minutes of more sleep during working days, which I feel a legitimiate suggestion, since I sleep from around 0:15 to around 6:25.

How do you guys sleep? Do you have an office job and work similar to me? Or do you have freelancing activities and you can schedule everything as you like or much more freely? Did your sleeping schedule ever get so weird that you ran into problems, maybe you had do to night shifts over a long period of time or because of unemployment? What do you think about methodologies that want to split the single one sleep during the night into a couple of hour long sleeps spread over the day? Any experiences?

Just a few short words to the article itself: It discussed the topic of some people just generally prefer to sleep in, because of their inner clock, and therefore they show a worse performance in school for example. Pretty interesting topic on its own.
