I'm one of the sandwich generation, except that in our case, it's a one-sided sandwich because we have elderly parents we're taking care of but no children. We have had to help our nieces and nephews a lot, though. One of our nieces is a single mother with a six year old and they lived with us when she first had him until she was able to get on her feet.
My husband is 54 and loves his job as a professor of Astronomy. He may never retire! I've found that dedicated astronomers rarely do. They can't stop looking for the answers and the questions keep on coming! I, on the other hand, consider myself semi-retired already because I work part-time at a job I like and manage all the money. When I went from full-time to part-time due to health problems, I started to become aware of our vast ignorance of all things financial around 10 years ago and started reading like crazy to make up for lost time. I taught myself enough about personal finance to at least fix our retirement asset allocation, start prepaying our mortgage (and refinanced to a much lower rate and a shorter term, 15-years), things like that. We were always very cautious and never got into credit card debt but we were clueless (and very disinterested) in financial matters. I finally realized that one of us had to get interested and start making decisions before it was too late. We started late as it was. Now we are debt-free except for the mortgage, which is going down, but not fast enough for my taste. I can't wait to be TOTALLY debt-free!
I am trying to teach the next generation to wise-up at a younger age so they don't have to play catch-up like we have. Some listen, some don't. At least they are exposed to it. We have learned a lot from our parents' mistakes.
