>> I consider awake to mean from 8AM to 12AM, you are getting at least 8 hours of sleep, right?
Must be nice to be a millionaire who works from home then stays up late every night. Is this Charlie sheen's jingle-writing character from 2 1/2 men? The rest of the working population gets up long before 8am. Work starts at 8am. School starts at 8am. Most people I know, at least those with jobs/kids, set their alarms for 6am. If I were to guess, the working population of the US will generally be awake between 6am and 11pm.
Or come join the military. 0400 is a very common alarm time. I'm at my desk by 0515 most mornings.
