Not sure how valid the ?fitness age? data that I see. I am 74, with a VO2 reading of 45- which says that is excellent and my fitness age is that of a 21 year old and states I am in the top 5% for my age and gender. My wife is glad that doesn?t correlate to other activities.:)
If you would see me getting in and out of my Miata you would know I am 74. Nick
