I am a night owl and like to stay up late!!! Most of the time i stay up till 4 or 5 am.
i am the opposite, early bed early rise
I've never heard of an early bird, but night owls are called B-people in Scandinavia.  Hootie Hoot.
that's funny, a new way of describing it.
Yes it is and I am starting to believe that i may have  delayed sleep-phase disorder, a difficulty waking up and going to sleep at the "correct" times.  LOL You day people always think you are right about everything. LOL
