Michael I respect your opinion and we can agree to disagree.
My point is the body needs some recovery periods/healing.
You can not run a car continously without service and rebuidling periods. The body kind of works the same way.

Overuse injuries can be caused or aggravated by:
• growth spurts or an imbalance between strength and flexibility
• inadequate warm-up
• excessive activity (for example, increased intensity, duration, or frequency of playing and/or training)
• playing the same sport year-round or multiple sports during the same season
• improper technique (for example, overextending on a pitch)
• unsuitable equipment (for example, nonsupportive athletic shoes)
