(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. ;-)
