A 1991 calculation was made to determine what, if any, additional health-care costs beyond the ordinary are borne by society at large for people who live a sedentary life. The figure reached was a lifetime average of $1,650. Thus people’s voluntary choice not to exercise places a significant burden on society.

Summarize Argument
The author concludes that people who choose not to exercise impose “significant” additional costs on society. Why? Because a calculation showed the average sedentary person contributes $1,650 in extra healthcare costs to society over their lifetime.

Notable Assumptions
The author assumes that a burden of $1,650 over each sedentary person’s lifetime adds up to a “significant” total. In addition, she assumes that people who live a sedentary life do so because they choose not to exercise.

A
Many people whose employment requires physical exertion do not choose to engage in regular physical exercise when they are not at work.
Such people may not be counted as sedentary. There’s no indication the 1991 calculation relied on an estimate of how many people live a sedentary lifestyle.
B
Exercise is a topic that is often omitted from discussion between doctor and patient during a patient’s visit.
Patients may still seek medical care for conditions caused by a sedentary lifestyle, even if that lifestyle is not identified as the cause. This helps explain why some people choose not to exercise, but doesn’t address any burden they might place on society.
C
Physical conditions that eventually require medical or nursing-home care often first predispose a person to adopt a sedentary life-style.
This implies those physical conditions are responsible for much of the healthcare burden, rather than voluntary decisions not to exercise. It challenges the author’s assumption that sedentary people simply choose to avoid exercise.
D
Individuals vary widely in the amount and kind of exercise they choose, when they do exercise regularly.
This refers to people who exercise regularly, not those with a sedentary lifestyle. It doesn’t say the collection of people with a sedentary lifestyle is ill-defined.
E
A regular program of moderate exercise tends to increase circulation, induce a feeling of well-being and energy, and decrease excess weight.
This offers more detail to the argument. These benefits of exercise help explain why a sedentary lifestyle is unhealthy—they don’t address the apparent burden people who don’t exercise place on society.
