A Tale of Three Hammers

Three carpenters each had their hammers ...

One carpenter didn't take care of it. He left it in the weather, where the sun faded and cracked the handle and the rain rusted it. He used it some, but the deterioration made it less usable, and unusable long before its time.

One carpenter kept his polished and oiled. He didn't do much else with it, but it was a beautiful hammer.

One carpenter took care of his as he used it. Eventually it wore out from usage, but it served him long and well.

Our bodies are our "hammers". They are intended to be used. They won't last forever, but if we take care of our bodies they usually will serve us well.
