This can be done, you can be actually taller. It is apparently an excruciating procedure that lasts for a year. Or more if you actually want to try to growth 6 inches (plus that is $150,000).
They do this by breaking your legs and inserting something that separates the bones by about a millimeter every day. It is completely inserted and control by a magnetic controller.
But this does not make you better at basketball, in fact they won’t do it for athletes. I can imagine why, your bones probably would not be as strong, because they are basically broken during the whole procedure. Luckily I’m already 6’4″ amazingly handsome, full of muscles, with beautiful women chasing me all the time.
