I used to have health issues that made sitting for long periods of time near impossible. As my team was aware, pretty much all meetings I had my camera off as I used the opportunity to walk around the house with wireless headphones.

My health issues are fixed now, thankfully, but I intend to continue doing that if possible, as it makes the experience far less tiring and I feel much more focused. I think the lack of video is as important a factor as the physical activity.
