That's a great photo and looks like a fantastic place to enjoy, but also like a terrible working seat.
I also roam a bit, but I wouldn't roam to a different place every day. There are certain properties for a healthy working place that I won't find everywhere, and can't afford to take the chances so often.
That said, working at home means we're free to make our own timing, which is unique and takes a little while to get used to. By now I feel completely comfortable in breaking out in the middle of the day, while there's still sunlight, to go do some sports outside or even just a walk or bike ride, and then come back later, take a good shower, and into the office for more action. I also enjoy working quite a bit in the evenings, so that helps with that sort of daytime break.
Obviously, people are not all equal, though, so what works well for some doesn't for others. If one is introspective enough, as most people in this field are, shouldn't be hard to keep the goals and constraints we operate under in mind and build a healthy working habit.
