I know that astronauts can lose some bone tissue after hanging out in space for awhile, so it only makes sense that the same thing would happen (probably to a lesser extent) if you were to hang out on the moon for awhile. If someone were to be born on and grow up on the moon would the lacking bone tissue cause them to be shorter? Or would the lower gravity level allow them to grow taller because their skeleton had less weight to carry? Or would it not matter because your DNA has the final say in how tall you will be?
