Want to live to be 100 years old?   Today it might not be such a wild idea.

Life expectancy at birth has increased by roughly 50 percent in the United States—from 48 for men and 51 for women in 1900 to 75 for men and 80 for women today.

While scientists attribute better medicine and sanitary conditions to the expanded life span, what will it take to live past the norm?   A recent Newsweek article discusses the impact of genetics and lifestyle on how long we live and offers interesting suggestions for you to consider, such as a calorie-restricted diet.   This is not for everyone but the benefits of limiting how much you eat and making better choices about what you eat are clear.

Genetic research is also under way to identify genes that can reverse ageing.  The goal may not be so much to let us live that much longer but to have a healthier life as we age.   That is good news.
