Well, if you're single with no spouse who relies on you for financial support, you probably don't need life insurance.
In fact, if you have life insurance through your employer, you may have more than enough to meet your current life insurance needs.
However, if your circumstances change, and say for instance you get married, start a family, buy a home - you may find that you need life insurance outside of the plan provided by your employer.
But, buying life insurance while you are young and healthy can guarantee your coverage when you need it, at a much lower rate than buying life insurance in the future, and if you're health changes, you may find you are unable to get insured when you need it most.
