I am definitely a morning person. My wife, son and daughter are definitely not :) Also, as I became older I became more of a morning person starting around age 45 or so... These days I usually wake up around 6 to 8 AM even though I don't have to wake up for work until 7:30 or 8 in the morning I often wake up at six in the morning and cannot go back to sleep.

I don't think morning people are better, like you said we are just earlier. I wake up ready to go and full of energy, my wife keeps commenting on it for me to slow down in the morning. But then the downside is that at 10 PM I am ready to shut down and she is full of energy :)
