You can state in a living will that, should you become incapable of expressing your wishes, you do not want any medical procedure or intervention that would only serve to prolong dying. Under state law, the treatment you are refusing shall not include a medical procedure for nourishment, or a procedure considered by your attending physician to provide comfort or alleviate pain. Artificial nourishment may be withdrawn if you say that it should not be provided for a single procedure. Or that it should only be continued for a specified period.
