One of the first things I do with clients is to start them planning for any possible future debilitating illness, or just coming to a natural end of life. I use the Plan Well Guide. It is focused on helping people plan for serious illness, but it can be used for any type of situation where you or a loved one may be incapacitated, or non-communicative.
