I have learned that in your 30's you feel like you have learned how to somehow deal with almost anything life can throw at you. In your 40's and 50's, you start to re-think that. In your 60's-life can be about having to start completely over in trying to make a rule book that you can use-trying to figure out how to make life make sense-almost like doing your teen years full of angst all over again-(only with a lumpy bumpy body this time! lol)
