While this does happen, and someday it will happen to me if I survive long enough, I gained close to two centimeters in height within six months of starting a regular weightlifting program which is heavy on squats. Apparently there are enough small support muscles along the spine that bulking all of them up buffed my height stat.

This is distinct from the practice teaching me a more upright posture, which it also did, this isn't subjective height, it's the kind you can measure at some gyms on the weight station in bare feet.

Edit: occurs to me this raises... certain questions! Nothing more biochemically interesting than creatine.
