Simple things to make emergencies easier:

1. Name an emergency contact on your cellphone
2. Check to see if you have an emergency contact listed in your RMV profile
3. Make sure a copy of your healthcare proxy is in your medical file or with your doctor
4. Give your proxy (person) a copy of the form
5. Leave basic instructions for anyone who might need to take over for a bit — things like:  who to call to take care of pets, where is the key to the bulkhead, what is the WiFi password, is there a financial advisor or CPA who might know about your finances, do you have a ‘go-to' handyman if there are house problems?

I like a basic (paper) list that a person can easily find. The times that I have needed to walk in and help out, electronic methods are not available.  Sometimes your person will just need that neighbor's name to walk the dog.  This can be simple (magnet on the fridge) or fancier, depending on your level of interest in list making.  The easier it is to find, the better.
