The logic of insurance is extremely simple, that is, financial compensation. Insurance is to save in advance every year a portion of the money that you don't feel any financial pressure on. Then when you need the money, you can exchange it for several times more or even a dozen times more of the compensation or insurance coverage.
Insurance is a tool for a forward-looking financial risk management.
Forward-looking: It is impossible to buy afterward, you can buy only when you are healthy. Also, it needs to be known in advance. When the risk comes, can this sum of money or the corresponding compensation range meet your real needs?
Financial risk: How many situations will cause the temporary and permanent interruption of cash flow? Can I arrange in advance a cash flow with constraints?
Risk management: The essence of insurance is a tool to transfer risks, which leverage the heavy losses that individual families cannot afford to insurance companies.
People are very vulnerable groups. Insurance is a guaranteed investment whether we go to work or retire later. If we plan for the future when we are still young, then the future may really be in our own hands.
