Fungus Eliminator Appoint someone to handle your affairs in case you become incapacitated. If something happens and you are unable to care for your own health, decide who will take charge of those decisions for you. Talk to them about what kinds of things you want done. You can't know if you will need a Health Care proxy, but have one in place just in case. It's hard to think about things like this, but it is sensible to plan for this kind of eventuality, whether young or old.
