6、des Mountains in Ecuador seem to share the secret of long life too. These peoples remain healthy in body and spirit despite the passage of time.

7、e their great 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.

12、e. Most of the longest lived peoples had parents and grand parents who also reached very old ages. Good family genes may, therefore, be one factor in living longer.
