Someone like yourself that probably does not have any money, I can understand why you do not understand.
Even my small estate being left to my children and grand children is a great concern, and benefit to myself, and YES when I die I will be very happy knowing that my heirs will receive this money.
You, on the other hand, is just a selfish person who has no concern about what happens after you leave this earth, that is fine, you have proven to all that you are only concerned with yourself.
