I had a long conversation with my wife years ago about our parents. I told her back then that they could live with us, so long as they were not a physical danger to our family and didn't require specialized care. Years go by and things change, I pretty much expect my sister to take care of my parents now. She has two kids, but has never left the house and has little prospect of marriage. My wife's parents are different. I wouldn't trust either of their sons, so what I told my wife stands.
I;ve taken a beating in the 401k's and I know I am taking a chance with keeping them. Pelosi wants to loot them, but I don't think she dares. I have 30 year horizon on all of my investments just yet.
