I know many women age 50 and beyond who appear to be entrapped in the same old routines, poised and mature but hampered by grim rigidity. I know others, though, who remain fun and adventurous, unafraid to stretch their comfort zone no matter how old they are and what anyone else thinks. They are the ones who can still party all night -– even if it is once every few months and it takes that long for them to recover.
