Who taught you how to use your body?

This is a reasonable question, and most people could not give a decent answer.
Did anyone teach you:

1. Healthy skeletal alignment
2. Optimal body use
3. How your muscles work
4. Coordination
5. Timing
6. How and why to relax your body
7. Balance
8. Proprioception (relative position of body parts/awareness of how much strength is being applied)
9. Rhythm
10. Mind/body unity
11. Leverage
12. Kinaesthetic awareness (knowing where you limbs are positioned without needing to look)
13. Biomechanics
14. Footwork
15. Biofeedback
16. Ambidextrous use of the limbs

Your parents probably did not teach this to you.
School did not teach it either.
PE or physical education in school translates to mean 'sport' and sport is not teaching you how to use the body for anything other than what the sport requires.
