Summarize the concept of "physical stillness" and explain why it is a deadly proposition

Answer 1

Underlying the concept of "physical stillness" is that even people with excellent exercise habits tend to spend most of the remainder of their day in a sedentary environment: For example, sitting behind a desk, sitting at a computer, reading, watching TV, and lying down. In essence, people spend most of their non-exercise time not moving.
If you are physically active or exercise seven times per week for 30 minutes a day, you will accumulate 210 weekly minutes of intentional activity. Even though you perceive yourself as being physically active because of this daily activity, the issue at hand is your physical stillness the rest of the day. Those 210 minutes translate into just 2 percent of the total 10,080 minutes available to you on a weekly basis. Thus, the difference between a regular exerciser and a sedentary individual is 30 minutes of activity per day. The other 98 percent of the time, most exercisers and sedentary people spend their time in very similar non-moving activities.
Research indicates that people who spend most of their day sitting have a greater risk of dying prematurely from all causes and an even greater risk of dying from cardiovascular disease. The data further indicate that death rates are still high for people who spend most of their day sitting, even though they meet the current minimum moderate-physical activity recommendations (30 minutes, at least five times per week).
