I bury myself in physical labor to keep my mind from racing. The exhaustion does its part, and the next day I feel a well-earned fatigue. But the thinking doesn't stop. I even think about thinking, and questioning why we pretend that the mental realm is so distinct from the physical. I "feel" tired, I "feel" sad. It's all physical, just a different muscle group. Conditioning, exercise, fatigue, injury- is the mind that unique?
