When considering most types of insurance policies, it can be easy to see if and why you need them.
You insure your car because the law says you have to. You insure your home contents because if you were burgled it would cost far more to replace everything than you would pay in insurance premiums.
It is usually pretty simple to figure out how much you want to insure these things for and for what length of time. When it comes to life insurance however, things are different.
