More or less what I was going for. Extended periods of standing (especially in the same position the entire time) can cause a lot of stress/strain on your back and shoulders etc. Over time it's known to cause problems and I think can wear down cartilage in your spine and neck? Not certain about that though.
I'm sorry I'm calling BS, that sounds more like a rumor than anything else. If it is true, please provide some studies to support it. This is how we get things like cellphones cause brain cancer (there are many much larger sources of EM radiation than your cell phone, your microwave for instance).
