Well, there may be several different reasons someone may not need life insurance coverage.
For instance, if you have no dependents you may not need life insurance.
Or, if no one relies on your income or financial support to get by, then maybe you don't need life insurance.
If you have the money saved to pay off your debts and pay for your funeral and burial costs, you probably don't need life insurance.
However, if you do have dependents, or someone who relies on you for financial support, or you don't have money saved to pay for your final expenses, you may want to consider buying life insurance.
