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
whats that called your inner clock
Oh sure, blame it on my Circadian rhythm .  All animals have one, but that doesn't explain why some animals are up during the day and others are up at night.
early to bed, early to rise, makes a man wealthy and wise
You are most likely correct.  Perhaps i am just suffering from a sleep inversion, where the sleep wake cycles are reversed.  I will have to visit my local sleep center to find out.  Thanks for talking to me and helping me with my sleep disorder. It has been a blast!!
