Sorry, I didn’t express myself well. Someone upthread mentioned a range for middle age, and that is what I was meaning. I think people start thinking of themselves as middle aged around 45 and move to the senior mindset around 65 when they retire. Actual middle age is probably more around the mid thirties, but if you ask a 35 year old if they are middle aged they will say “No way,”. 40 is also a good number, but I still think most people would consider themselves young at 40. Circumstances probably play into it a lot also. I would imagine someone who has never been married at 40 will feel differently than a couple who married young, and their children are grown up and perhaps married themselves.
