Koreans workers burn around 2266 hours on the average in 2007.
Polish were second with 1953 hours
Japan: 1808 hours
USA: 1798 hours
France: 1457 hours
Germany: 1353 hours

So what about productivity? Not really in the same order for sure :-)
per some of the Wikepedia entries ...
So Working smarter would mean then that I am able to spend less time at work and maybe try to get closer to the 8-8-8 balance of work-sleep-social kind of equation the industrial revolution brought to us? There is enough data out there on the sleep part that we all need 7-8 hours of sleep every day :-)
Could it be then that the remaining 8+8 gets a new twist in terms of how you leverage social media?
