What benefits can you get from purchasing life insurance?

The main purpose of life insurance is to get life benefits at the insured's death, to be paid to the family or business, charity, trust, etc.
However, there are many "living benefits" of life insurance, that may be paid if the insured survives an accident or illness, but is unable to work for a period of time. Other benefits are paid in a lump sum at first diagnosis of a covered illness: cancer, stroke, heart attack, Alzheimers, major burns, etc.
These are optional riders that can be added to your life insurance policy.
