Final answer:
Maintaining good health and decreasing the death benefit can lower insurance premiums, while taking up smoking may increase them.
Explanation:
Maintaining good health would most likely contribute toward lowering the premium a policyholder pays. This is because individuals in good health are generally considered lower risk for insurers, leading to lower premiums.
Decreasing the death benefit could also contribute to lowering the premium, as a lower death benefit means less financial liability for the insurance company.
Taking up smoking would likely increase the premium since smoking is associated with higher health risks.
