Last Friday I told Glenn that my legs were hurting me so much that I was having trouble standing up and walking around and then on Friday night I woke in the middle of the night with the worst double Charlie horse I’ve ever had in my right leg.

Not only was I not getting enough potassium (I've fixed that), but I wasn’t getting up and walking around enough.  I sit in the Hawk studio for five hours a day, six days a week and sometimes I get so consumed in what I’m doing- whether it’s the article I’m writing or the caller I’m talking to on the phone that I forget to get up and walk around every hour.  And that can lead to something even more serious than Charlie horses.

It looks like “prolonged periods” of sitting each day–as little as four hours a day–increase a person’s risk of diabetes and heart disease and doctors are calling this "sitting disease." Yikes!

And what’s worse is that even daily physical activity such as running is enough to reverse the effects. The only thing that works is standing up.

Keep this in mind the next time you’re camped out at your desk.  It could save your life.
