If you have a serious illness, you may not be able to buy it. But if you have recovered from a serious illness and recovered well, you will have the opportunity to apply for insurance coverage from the insurance company. If the situation is not serious, there is a chance to buy critical illness insurance again. Therefore, our critical illness insurance needs to be planned in advance, because we don't know when the risk will come, and the younger we are, the lower the cost of insuring critical illness insurance. Not to mention that the premium is more expensive when you are old, and your physical condition is not as good as when you were young. There may be various problems when you apply for insurance.
