I feel like Carr's analysis was overly optimistic. Even in the aggregate, it seems really doubtful that 20 years of burning ~12 calories a day is anywhere near as effective as integrating breaks into your workday and walking around more. It's great that folks here have managed to ease some of the chronic spinal/back pain they're experiencing. But that's really the only positive effect I feel we can link with some level of certainty to standing (within the context of office work).
