Wouldn't it be nice to be ageless

I saw my parents and in-laws last week and I realized that they are getting to the point where they aren't getting around very well at all. My husband doesn't want to deal with it until it actually happens but I think we need to have a plan in case one or more of them becomes disabled. I know we are not alone being a middle class family with a kid ready to leave for college and having elderly parents that may need care in the not too distant future. I have no doubt it's going to be a tough road financially and emotionally for us. I just read the reviews on How to Care for Aging Parents
by Virginia Morris. That looks like a book that might be worthwhile to read.
