Do you have an advanced directive or a medical power of attorney filled out and stored somewhere safe? I bet you don't. An advanced directive is simply a form that expresses your wishes ahead of time for what type of medical care you want in case you are unable to make decisions for yourself. Basically what it boils down to is do you want to be kept on life support if you are stuck in a persistent vegetative state from which you will never recover? Here is the form, at least for Texans, for this advanced directive:

A Medical Power of Attorney is a firm that appoints someone to act on your behalf should a doctor declare you incompetent to make medical decisions on your own. Here is the form for that:

If you are not in Texas, you can just Google the terms and you will find thousands of them. If you do not have a set of these, you should probably hook it up. If your parents are dead, and you and your better half both have an issue where you both are turned into vegetables, you are going to want someone you trust to be making decisions in regards to your medical care, and you also are going to want the doctor to work off of your own wishes as expressed in the advanced directive. There have been tons of lawsuits and such based on various state to state laws in regards to these matters which could have been avoided had victims just been smart enough to plan ahead. Also, you don't want to put anyone in the bizarre scenario to have make medical decisions for you, if they have no idea what your wishes are.

Anyway, so those are the forms. Fill them out. In the forms, make sure to mark that you do NOT want to be put on permanent life support. You want to die. You do not want to be a carrot. Don't make your family suffer, or sink into unimaginable debt because you are too stupid to understand what being a potato really means. Technology will not come along in 25 years that will allow you to return to normal life. A divine miracle will not occur that will make every thing OK again. The two forms are setup for scenarios where you CAN NO LONGER FUNCTION. Under such circumstances, you won't have very much fun for the duration of your tenure on planet Earth, so just make things easier on everyone and die. Don't be so selfish that you make your family feel guilty forever for abandoning you while you spend your remaining years as a broccoli.

Do it.. NOW!
