Life insurance agents specialize in selling policies that pay beneficiaries when a policyholder dies. Depending on the policyholder’s circumstances, a cash-value policy can be designed to provide retirement income, funds for the education of children, or other benefits. Life insurance agents also sell annuities that promise a retirement income. Health insurance agents sell health insurance policies that cover the costs of medical care and loss of income due to illness or injury. They also may sell dental insurance and short- and long-term-disability insurance policies.
