There is uncertainty in life and insurance is designed to lessen the burden of this uncertainty. The principle of operation is simple, the insurer (that is Blue Cross Insurance company or Blue Shield in this case) pays the medical costs of the insured (you) if the insured becomes sick due to covered causes like disease, disability, accident etc. In return the insured (you) pays a monthly or annual premium (a monetary amount usually around 200 dollars a month, however the exact amount varies according to the insurance plan purchased) to the insurer. As a general rule, the larger number of people in the insurance group, the lesser is the premium. This is due to the distribution of costs.
