How can one's biological age out weighs one's chronological age?

Join Dr. Cheryl Cottle and her guest Dr. Carol Soloway on Women in Business Radio on Monday 4 August, as she introduces a new segment on how one's chronological age is different from their biological age. Does it have an impact on how our health and fitness affect our well-being and balance as entrepreneurs. Is it achievable? Or does it requires a woman with particular attributes to have her chronological age out weighs her biological age? When a call was made to reach women with the experience Dr. Carol Soloway wrote reminding me of our interview just a couple weeks ago. She reminded me that she got married at 60 and she was also an author; and added that she believes that being mentally active, facilitates optimum health. Dr. Soloway also reminded me that she has had the experience (and is living it) and will love to share her perception and experience. 

This topic is dear to me, because I have met women who does not look their chronological age; but looks years younger, but it is rare. I was drawn to the topic after reading and seeing a photograph of 4 women taken in 1916 in Washington D.C at the "Convention of Former Slaves." They were age 104, 105, 110 and 125 year old. (Source: Harris & Ewing Collection/Library of Congress) They looked quite fit physically and to be a part of an audience that celebrated the emancipation of slavery, reflect that they were also mentally sound. The image of these women begs me to ask the question, what is responsible for their health and longevity? And why is it that women today are not reaching those ages? I recently saw a photograph of a guest of mine, who is in her seventies and looks about 20 years younger. I had to investigate whether it is a doable for all women. What is the secret of life? Is it a secret?
