Personnel officer: The exorbitant cost of our health-insurance benefits reflects the high dollar amount of medical expenses incurred by our employees  Employees who are out of shape, as a group, have higher doctor bills and longer hospital stays than do their colleagues who are fit
Ttherefore, since we must reduce our health-insurance costs, we should offer a rigorous fitness program of jogging and weight lifting to all employees, and require employees who are out of shape to participate
The medical expenses incurred by fit people who participate in a program of jogging and weight lifting are less than those incurred by fit people who do not participate in such a program.
