I have been doing this for about a month now. I am kicking myself for not having made the switch anytime sooner. Come to think of it, I feel humans are just not designed to sit for long hours in chairs. Standing position is natural. You feel free and are less constrained compared to a sitting position. Posture changes happen a lot more; And breaks you take are more active or sometimes continuous. They also become less of a chore.

If there is an iota of doubt in your mind, that sitting for long hours is somehow screwing up your back then please switch to a standing desk.
