Our Credit to LINDA POON who first wrote this for NPR. All of you lazy, fat guys need to look at this. I preach to my self as well. My doctor told me that anyone who has a desk job should get up and walk around a bit every 15 or 20 minutes, to reduce a host of physical maladies and reduce risk for debilitating illness. Even on airplanes, we are advised to get up and walk every 20 minutes. As the blood thickens on long air trips there is a high incidence of people who have health problems the first hour after landing. So....get up and move around! Ben Boothe, Boothe Global Perspectives
Sure, it's relaxing. But all those hours on the sofa may make it hard to actually stand up on your own.
The more you sit, the less physically active you are, which can lead to all sorts of health problems, including an early death.
