Morning larks and Night owls

There are 2 types of people:

• Morning larks – wake up early, go to bed early.
• Night owls – wake up late, go to bed late.

Morning larks is about 40% of population, 30% is the second type. Other 30% is evening type.

This types are not a problem and not something we can change, it is written in DNA. Long time ago it was used to reduce the time when all people sleep and no-one secures the group.
