Email is bad for you – it’s official. A study by Ashlee McGuire, a graduate student from Queens University in Ontario, says that walking over to a co-worker rather than sending them an email has long-term health benefits. Well, yeah, if all you do all day is sit at a desk and look at a screen attached to a box it’s likely that you will end up inside a bigger box sooner rather than later. But don’t give up email, just do some exercise nit wit.
