> Wait till standing desks have been in fashion for some decades and you'll start seeing stories about people getting Thrombophlebitis in their legs.

Sitting for too long causes Thrombophlebitis too.

Standing desks are fine. Just like sitting, you don't stand all day. You take breaks. You move around.

The greatest benefit of a standing desk is you're more readily able to take breaks. You're already up. I think anyone with a sitting day job can attest to skipping breaks because of the effort of standing up. Yes, you heard me correctly, and it's true. Sometimes you're so into a problem or issue your brain tells you to skip taking a break because it's not worth the effort of getting up.

I've seen quite a few older folks who had the condition and they usually shared one thing: their careers involved standing most of their working day (store clerks, masseurs and such).

So from my (possibly subjective) experience, I'd say standing all day is worse than sitting all day as far as T-phlebitis goes.
