Why do people get old?

We start aging the day we are born. As we get older, more prominent symptoms appear. Some people age early because of their lifestyles. (drinking excessively, drugs, etc.) Keeping our bodies & minds healthy, may delay the inevitable for some. Genetics also plays a key factor in the aging factor. People of Scandinavian descent, such as myself, tend to age gracefully. I'm not bragging, I'm referring to people who ask my age & can't believe it.
