Everything is dangerous. Everything. Including sitting down: From the CBS San Francisco story:

But now new research shows sitting for long stretches of time may be just as dangerous. “Smoking certainly is a major cardiovascular risk factor and sitting can be equivalent in many cases,” explained Dr. David Coven. Dr. Coven is a cardiologist. He says several new studies show prolonged sitting is now being linked to increased risk of heart disease, obesity, diabetes, cancer, and even early death.

I love my SHSers. Stand up! Walk! Climb some stairs. But don’t read the blog on your smart phone while walking. You might get hit by a car.
