​Maybe spears to the bum of a mammoth did bring about the invention of Acupuncture??

​As the legend goes, it was ancient Chinese warriors around 3000 years ago, fighting on the battle fields that first developed the idea of Acupuncture when they discovered various ailments and injuries improved when they were stabbed by arrows and swords in strange places.
The first acupuncture needles were actually SHARPENED STONES and SHARP LONG BONES!!
And you were worried about those tiny, thin needles we use in clinic!
