Love this question. I just recently decided to let my grey hair grow out and I'm having tons of health issues but I think what keeps me feeling young is that I have no desire to quit exploring and taking on new adventures. Whether your 20, 40 or 80 -- once you quit being productive, stop learning and no longer expand your horizons -- then you're already OLD. 8-)
I am new to the 40's and just wondered what you amazing ladies consider your fountain of youth?
