This comes from MSNBC.

They released a story today listing 7 bad bedtime habits.  These usually keep people awake instead of helping them get to sleep.  One habit is reading a book.  Now, I like reading books, and I prefer the actual physsical book as opposed to an e-book, but reading puts me into a relaxed state that naturally puts me to sleep.  In fact, I can’t read a book during the day as it is a surefire way to get me to take an afternoon nap.

One habit they listed that I totally agree with is Facebooking in bed.  I enjoy Facebook and use it to keep track of distant friends, but doing so late at night is just not good.  It’s like flipping through the TV late at night when you know you should be sleeping.  Blogging is the same way.  Your ideas can wait until morning.  Your sleep and the benefits from sleeping mean more than what your blog says or your Facebook status.
