Would you buy something/anything without having a good reason ?
I can understand an impulse buy of a CD or a shirt but a life assurance policy ?
Then again, we are all free to spend our money as we like, well within the constraints of the law, I suppose, but the fact that your a re asking the questions implies that you are looking for a rational reason for buying this product/service. If you feel that when you die, you would like to leave more money to your dependants/next of kin/state then that's a good reason to buy the policy - in fact, it's the only reason.
