Everyone's talking about qi. Here's some ideas: It's the difference between a plant that's alive and one that's about to die — same soil, same water, same sunlight. Something is moving in one that isn't moving in the other. TCM calls that something qi. In your body, it shows up as: → The energy you have (or don't have) when you wake up → How well your digestion actually works → Whether you feel clear-headed or foggy by 3pm → How quickly you bounce back after stress or illness
