That The Human Body Was Designed To Live Forever.  Examples are:

 

The human BONES are totally replaced every 10 to 15 years.

 

The human SURFACE SKIN is replaced every (1) month (30 to 39 days).

 

The human RED BLOOD CELLS are replaced every 120 days.

 

The human body’s ENTIRE CELLS are replaced every 7 to 10 years.

 

The human LIVER is replaced every 300 to 500 days.

 

The human body replaces its INTESTINAL EPITHELIAL CELLS every 5 days.

 

The human INTERNAL INTESTINAL CELLS are replaced every 16 years.

 

The human HIPPOCAMPAL NEURONS (Brain Tissue) are replaced every 20 to 30 years.

 

The human body’s HEART ENDOTHELIAL CELLS are replaced every 6 years.

 

The human body’s FAT STORAGE CELLS are replaced every 10 years.

 

Note:  Some of the human body’s cells stop growing when they are MATURE; but of course, keep on functioning.

 

Also, according to Job 12:10, mankind lives or dies because:  “In Whose hand [God’s] is the soul of every living thing, and the breath of all mankind.”

 

In other words, the “Main Theme” of the Bible is:  “The Character of Man[kind] and the Character of God.”  Se were designed to become God-Like.
