Apologies if this has already been asked, I'm sure it has. I tried using the search but it kept spitting out errors for some reason.

If I was to say get Femur Lengthening, 5cm and then recover for 2 years, would I be able to get another 5cm lengthened? If not, how come?

Does anyone know of anyone who has had something like this done? My dream height would require about 15 - 20 cm lengthening, ideally the 20cm would be perfect.
