Comprehensive car insurance covers damages from an "act of God," or events that are not caused by a car driving into something else. An "act of God" can include things like damage from a heavy tree branch falling on your car. Since you have no control over when or why a tree branch would fall on your car, this kind of accident would be covered under your comprehensive policy.
Once you know the approximate value of your car and the cost to carry collision coverage, then you can make an informed decision about purchasing that coverage. Many people find that it's a good idea to cover newer cars, but as cars get older, their values decrease, and you might consider omitting or dropping this coverage to save money on your auto insurance.
Life insurance premiums depend on the age of the insured party. Because younger people are less likely to die than older people, younger people typically pay lower life insurance costs. Gender plays a similar role. Because women tend to live longer than men, women tend to pay lower premiums. Engaging in risky activities increases insurance costs. For example, a racecar driver faces an increased risk of death and, as a result, may pay high life insurance premiums or be denied coverage.
