Nevertheless, the word aging itself has many meanings too.  There is that notion when white hairs start to become evident that you are old.  There is also that connotation that when people retire from work, it means that they are aged already.  However, there are those individuals that defy the meaning of aging.  Some 70 or 80 years old are still active in activities that even younger people cannot do.  Having an active life is important in order to keep your body fit and your muscles working properly.

However, it does not mean that when you take good care of your aging body, that you will live longer.  Some things for consideration in this aspect are heredity, health care and lifestyle.  If it runs in the family that people have a long life expectancy, then most likely, you will live longer too.  Health care means that they try to avoid smoking, excessive drinking and the likes.
