Planning ahead is excellent idea rather than waiting for an emergency.

This article has helpful information on what documents and other things that should have as you age.

I would also suggest checking what local resources are available. Eldercare is one organization that can provide information you may be looking for:

You may ask friends and relatives who have had experience with local facilities.

Check your state's Humans Services web site, example, MN has this site: https://mn.gov/dhs/people-we-serve/seniors/
