You lose 7% of salary while you are snoozing

 But just keep on sleeping because 10 years ago you lost the entire 13% and in 10 years time you will propably be at the same level as A-human. These are some of the shocking numbers of Rockwool Foundation publication Sleep - marriage, income and health - which you can read here as a summary and here in full length.

39% are A-people and only 18% B. C people are up early and to bed late - it's 29%. Late up and early to bed is the pattern for the 14% D people.

Are you man and A-human, you have most likely a long-term relationship. Are you a woman and 22 years old, you sleep around. one hour over a 22-year-old man - as 40-year-old sleeping in same period of time.

Are you Danish, you get less sleep compared to all other countries in Europe. As a general rule in Europe the less people sleep, the richer (measured by GDP) is the country!

So you can think about that tonight!
