Cross-cultural studies on personality traits have shown that ____.

Many scientists believe that for humans at least, there is a natural span of life. That is, there is a limit beyond which human life cannot extend, regardless of advances in medical science. Currently, the maximum life span in developed countries is around $120$ years, and evidence suggests that it has been that way since Roman times. However, with improvements in medical care, the average life span has increased significantly during the past century. Sketch a sequence of survivorship curves that illustrates an increasing average life span with the exact maximum life span.
