just in case

Dear Bobby and Lizzy,
This post will be a little morbid, because it addresses my final wishes. As I expressed in my first post, I hope to live a long time still, but just in case fate has other plans for me, these are my final wishes:
1. I do NOT want to be preserved on life support systems once it is clear that I have suffered irreversible damage that will prevent me from leading a normal and independent life. As a matter of fact, I do not want to be in any dependent state of existence---when I am no longer able to care for myself, my strong desire is to find a dignified and expedient way to die;
2. Upon my death, I want to be cremated(after any parts of my body have been harvested for organ donor or related medical purposes), and my ashes disposed of in any way you and Nancy wish. Please find the least expensive arrangement available---the LAST thing I want is to waste valuable resources on a funeral director's sales pitch;
3. At the moment, I have one major financial goal, and that is to help Lizzy complete her baccalaureate education, as we have done now for Christopher, Bobby, and Emma. Once this goal has been met, whatever modest estate is left, my wish is that it be used to help Nancy live comfortably, and any balance to be shared equally among our four children. Although I hope to help all of our kids a little with the cost of graduate school, I trust that you will be able to pay most of those expenses through your own resourcefulness.
These wishes have no legal effect. Nancy and I have a Trust which generally spells these out in legal form, but I want you to know of my wishes to guide you if necessary.
Love,
Dad
