Cancer and the Single Patient: A Special Need for Help

As a single person, this situation has crossed my mind with some frequency. While I am healthy now at age 60, I am living 1500 miles from family. My mother lives with me - she's 81 and in excellent health, and her mother lived to 89 (died in her sleep), so apparently I have good genes, but I still try to plan for eventually needing outside care by purchasing long term care insurance in the next couple of years. Does anyone who is in a similar situation have other suggestions?
