B-Society will create a new daily rhythm in schools and other institutions as an alternative to the current rhythm of “early at work and early at home”.

The society’s time structures based on habits of the early riser’s are not untouchable natural laws even though it can easily seem so from looking at the ways in which we have organized our lives. No. The ‘owl’ has got the right to say: “Give me the late riser’s rhythm at work, at home and in society. Let me come to work at 11:00 and go home at 20:00. Let me have quiet mornings to read my newspaper and ease into the day gently and peacefully”.

Science has shown that our biological rhythms through “a day” (i.e. “Nychthemeron” = “a day and a night) are regulated by a so-called “clock gene”.
 
B-persons have a clock gene lasting 25-27 hours, whereas A-persons have one that runs for approximately 23 hours.
    
Every individual has their own biological rhythm (known as the “Circadian rhythm”), which means we have our very own sense of time and planning of time. There are lots of different kinds of circadian rhythms. Most people are B-persons, which means that their circadian rhythm has a cycle that runs through 25 hours or more.

 B-persons have therefore a tendency to stretch their "nychthemeron”. A B-person finds it easy to stay awake in the evening; but has difficulties waking up in the morning – the time where the A-persons are the most active. Each human being has this so-called inner clock, which is regulated by the clock-gene.

A B-person stays awake until late at night – and goes to bed at 1 or 2 a.m. and sleeps a little longer in the morning.

If a B-person and an A-person go to sleep at the same time and rise early the same time next day, their mornings will be experienced differently, as the body-temperature of the A-person is higher than that of the B-person at this point. The B-person has therefore a very good reason for feeling drowsy, as it is still ”night” (”time for sleep”) for the B-person.

One family has been followed and tested for several years in the USA. They have "FASPS", familial advanced sleep phase syndrome. See, for example, http://www.hhmi.org/news/ptacek2.html. A group of scientists has found out that humans, who are extreme A-persons, have a genetic flaw or disturbance.

15 – 25 percent of the population is made of B-persons, 10 -15 percent are A-persons. The rest of the population are more or less either one or the other, or something in between.
