Oh, height implants! They don't do it in the U.S., but I think they do it is Russia and China. They break the bones in your arms and legs, stretch them apart with braces, and the bone heals up longer.
Can I sleep through the healing process? It sounds incredibly painful.
I can distinctly remember watching a talk show, Phil Donahue, back in the 1970's or 1980's.
He did a show where the Elizardi (?) procedure was done to youngsters to lengthen their arms. Donahue asked a boy what was the first thing he was going to do when he the procedure was finished. "Put my hands in my pockets." Talk about making me appreciate life. I recall the episode at least 2 or 3 times a year to refuel my gratitude.
