Just noticed this thread...
Contrary to most of the people who have posted here I would like to be shorter. I am 6'4 and shopping is a pain. I have an odd upper body- arms are too long, torso is too long, shoulders are too narrow, etc- and buying shirts that fit right is a pain.
I would also get rid of this damn speech impediment. It has gotten better as I aged but is still the one thing that I feel is really holding me back from being the confident man I could be.
