I'm not against the concept of "investing in your health". That said, while there have of course been studies that show sitting isn't so hot for your health, have there been studies that actually show standing desks are good? Varicose veins are not high on my list of to-dos, you know.
It seems that the important part is that you're moving throughout the day. Personally, when I'm switching between standing and sitting throughout the day I have more energy and tend to move around a lot more. If I didn't do this, I'd end up sitting for periods of 4+ hours at a time.
As a CTO I manage development and technology for the company, which means I'm up and around the office (and out) for meetings and touching base with other departments. If I were an engineer I'd likely utilize a standing desk less. I personally don't enjoy coding standing up.
