Sitting = Smoking

The new doctor said "sit equals today to what it was smoking" is not an exaggeration, tells the October edition of the "Mayo Clinic Health Letter." While most people do not smoke, everyone sits and many do every day for quite some time. In fact, many employees sit for 15 hours a day.
The underlying message is becoming more clear: It is important for health, to exercise daily, but also have to pay attention to the time we spend sit.
