WorldExercise & the BodyDrive a treadmill against a living body — a heart that lags the belt, lactate past the threshold, a tank that empties, sweat that dries you out, muscles that warm — then plan the weeks: taper to peak on race day, and lift, rest, grow
WorldInside a PlantCut a stem open, then ride the water up the xylem and the sugar down the phloem
WorldUsing a MicroscopeMount, stain, hunt, focus — and measure a cell in micrometres with a graticule you calibrate yourself
WorldBalance & Body Mechanics (Yoga)Drag a body with real masses into eight asanas and let its own mechanics judge you — joint angles, the stack of ear over hip over ankle, the centre of mass over the feet, a floor that is wherever the lowest point rests — then breathe with it and find the breath that swings the heart
