if you treat it like a 'desk job' that's what it will end up being for you.
I couldn't agree more, thanks for the insights.
For me as an independent designer with mostly foreign clients, it has become quite too much a desk job.
I do travel to clients but Skype with screen sharing is a good solution to work remotely as well.
So I'm interested in adding a small standing desk to my studio, I believe it will increase productivity and well, general household happiness levels.
