Very true that we sit by our screens way too much. Any reasonable work away from it is probably for the best. On this note I would like to share a really good tip (but slightly out of topic) that I got in the comments on some HN post some time ago; don’t use your phone or Internet until late morning, or at least after having really dug in to work for the day. This really helps to focus on the work at hand and avoid distractions.
