John, age 52, is overweight, smokes, and had a mild heart attack five years ago. Ignoring the advice of his physician, he refuses to exercise, lose weight, and quit smoking. John owns a $25,000 participating ordinary life policy that he purchased 20 years ago. A life insurance agent approached John and proposed that he replace the older policy with a new life insurance policy. The agent claims the new policy is superior to the older policy that was purchased years ago. Despite John's health problems, the agent claims that John can get life insurance from his company. What factors should John consider before replacing the older policy with a new policy?
