Alright, so the research has been conducted, verified, and introduced changes in the lives of teenagers. Now let's move on to adults. Where's my 10am start time at work???
The idea that 9am is holy and if you're not there you're not productive is just flatly contradicted by my personal experience.
Even though I'm a night person though, I still find myself much more productive in the morning.
Working until 7 is a drag.
It's also a great environment for early risers. I get in at 8, and I'm a machine through 10:00 every day
I understand the need for many workplace to have close to standard hours but freedom to alter hours given your day should be a must. Where I did my internship had people arrive from 8-10ish and leave 4-6 and was very generous about people being able to come in late or leave early if they had something to do on the day.
Did I mention that we are looking to expanding our team in Cambridge, UK? (Send me an email, if you'd like more information. You can also find some positions on http://www.citrix.com/English/aboutCitrix/employment/feature...)
As an adult, your [highest daytime alertness is at 10AM]( http://en.wikipedia.org/wiki/File:Biological_clock_human.PNG). You don't go from drowsy to alert instantly, so 9AM to 10AM is one of the most alert parts of your day.
My biological clock is about 3 hours behind, in relation to the light-dark cycle. I become tremendously productive just before noon.
My work often starts at 11am, sometimes 9am, sometimes 7am. I finish at 6pm-ish though sometimes 5pm, sometimes, 9:30 and sometimes 2am or 3am. If a 7 hour day sounds good, it can be but generally I'd do a couple of extras to avoid doing a 14 or 21 day cycle without a proper break.
Thankfully I hate routine.
I do have a second job too.
