As a Finn, I really can't imagine doing an office job 16 hours a day for a sustained period of time; even the standard seven and a half is a challenge to fill with productive work every day (certainly you could idle at the office but that doesn't count as working). A single 16-hour day is doable if there's really something to do, but it would cause me to take the next day off.

Doing what I do currently, constant 16 hour days would almost certainly result in hospitalization in a few weeks.

At least in programming you can easily see who do put in extra effort be it studying/playing with new tech or writing new software and thous who for it is only a 9 to 5 job.

The former people seem to produce way better quality code and ideas compared to latter, but that is to be expected since they are in one way or another immersed in the "world of programming" more than others.

(I'm not a Finn) I struggle to think what could possibly benefit from someone spending 16 hours devoted to something. Maybe something on the creative side of things like writing a book/novel?? But even then, I would guess that it would get the creative juices moving even more if you actually step away from the computer/typewriter/notebook for a time! What the heck in a business/enterprise environment benefits from anyone being there 16 hours in a day? Seems more and more like a hamster running inside a wheel to me. ;-)
