Anti aging through physical exercise

If a you move enough and fit in the classification of physically active people, then from biological point of view, you are "saving" about 10 years of your real age. This is shown from a British medical research.
According to the authors of this research this is a "strong signal for the potential effect of regular movement" and they recommend "at least 30 minutes average intense movement (such as fast walking), at least 5 times a week". For the fans of more intense exercise (like jogging) this should be 20 minutes at least 3 times a week.
The British scientists have published the results of their observation on over 2400 people in the Archives of Internal Medicine magazine.
Their data shows that the benefits from physical exercise is found no matter other factors in life such as age, gender, BMI or social/economical position in society.
"People who move enough are different from those who lead a still life in many things. As a whole it could be said that biological aging of the first type is about 10 years less than their real age" make the conclusion the British scientists.
