From US:

I don't ever recall working less than a 60 hour week, and most of the time it has been more. There have been a few years when I've taken two weeks of vacation, but they were taken a week at a time. Most people here retire at least by age 65, but I'm 6 years past that and still working the same amount.

I really don't think it is so much a matter of countries as it is a matter of people. I, for example, can tolerate a half hour doing nothing but watching TV or some such mindless thing, but any more than that drives me up a wall.

My point is, we do (as much as we can) what we are happiest doing. For some it is work, for others, something else.
