Policies typically use vague language when referring to acts of terrorism, but they are generally insured by the comprehensive portion of your policy. For example, if there is an act of terror and you need to make a claim on your car, that can only be made if you have comprehensive coverage. Since some circumstances are out of our control, comprehensive insurance is certainly important to have in your policy.
Collision coverage is limited to the actual cash value of the vehicle, and requires a deductible, which is the amount you'll need to pay before receiving benefits. Higher deductibles lower your premium but increase the amount you must pay out of your own pocket if a loss occurs. Ask yourself how much you would be willing to pay on short notice in order to save on your premium, or talk to your agent.
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.
