My parents are getting old and are not in the best of health. My father is a heavy smoker - and there is absolutely nothing you can say to him about it. Both of my parents don't each healthy and don't exercise. Also, cancer runs on my mothers side of the family. My father has a pension and I am in the middle of helping my mom figure out her retirement allocation. My question is, how should they prepare for old age and health care costs? If one or both of my parents get cancer, will they go bankrupt paying for the bills - is there a way to prevent this? I guess I'm asking what are their options/what should I look into?
