Yup ... that is a Kitchenaid timer next to my keyboard. It gets set for 10 - 15 minutes most every time I sit down at the computer (which is a lot). When it goes off I get up and do something ... lift weights, yoga (or qikung), do some dishes or just walk outside for a couple minutes.There is overwhelming evidence that sitting for prolonged periods of time is really bad for your health.
Anyway ... something to think about if you are spending a whole lot of time seated.
