Bro,
I'm standing 5' 5" right now, when I sit on the toilet my legs swing.
I have absolutely no desire to go thru procedure you are considering. Not even a thought! Your body will just never be the same… I don’t see how it could… Your bones are your core!
Don’t fuck with that.
PS: Bing tall is overated. Aside from the obvious reach advantage. I have not seen anybody do better than me, or acomplish more just because they are taller. If anything, I think I do better and try harder.
