     In the Caucasus Mountains of Russia, nearly fifty out of every one hundred thousand people live to

celebrate their hundredth birthday, and many don't stop at 100! By comparison, in America only three

in one hundred thousand people reach 100. But these Russian old people aren't alone. The Pakistanis,

who live in the Himalaya Mountains and the Ecuadorans of the Andes Mountains , seem to share the

secret of long life, too. These people remain healthy in body and spirit in spite of the passage of time.

While many persons in industrial societies become weak and ill in their 60s and 70s, some Caucasians,

aged 110 to 140, work in the fields beside their great grandchildren. Even the idea of aging is foreign to

them. When asked, "at what age does youth end?" most of these old people had no answer. Several

replied, "well perhaps at the age of 80," and the very youngest estimate was at the age of 60.

     What accounts for this ability to survive to such an old age, and to survive so well? First of all, hard

physical work is a way of life for all these long - lived people. They begin their long days of physical

labor as children and never seem to stop.

     All these people get healthful rewards from the environment in which they work. They all come from

mountainous regions. This reduced - oxygen environment makes the heart and blood vessel system

stronger.

     Another factor that may contribute to the good health of these people is their isolation. To a great

extent, they are separated from the pressures and worries of industrial society. Inherited(遗传的)factors

also play some role.

     It is clear that isolation from urban pressures and pollution, clean mountain air, daily hard work,

moderate diets, good genes, and a youthful approach to life all contribute to the health and long life of all

these people.
