As medical science has advanced, so has life expectancy in the developed nations that benefit from those advancements. In the United States alone, the average life expectancy for all races and sexes has jumped from 70.9 years in 1970 to 77. 9 years in 2005 [source: CDC].
The advancement of medical science has also led to interest in living longer and healthier lives. As a result of this vigorous interest, a booming cottage industry dedicated to longevity has emerged over the past couple of decades.

What follows are five easy methods you can try to stay young and healthy longer.
