I would change the following:
Less facial/body hair, I don't have alot fortunately, but I would like to lose what I do have - will problably do electro for facial hair;
Age is a good one as others have mentioned, I would like to be younger and know what I know now;
Feet and hands, they are too big for my taste and I wish they were smaller. I really feel it when shopping for shoes, there are more choices for smaller feet, and I love shoes and shopping for shoes.
That's it for me.
