Late night ramble

OK so this isn't a walk in the dark...

I'm just wondering what millions of people who are tired, and who should be in bed sleeping, are actually doing with their time late at night.

I also wonder whether people regret the lack of sleep in the morning regardless or whether if the activity was "good" then people buy the payback.

I'm not sure surfing, e-mailing and blogging count as "good" so maybe I ought to listen to my droopy eyelids.
