Courtney, totally normal to itch when sweating, my scalp itches the first few minutes when I sweat... I think it's the salt in our sweat and the opening of the pores...
As for the breast, I think a lot of it has to do with genetics, if you have a family of big breasted women, chances are you won't lose much there... You can't spot reduce but you can build the muscles that are above and below the the breast, and this will give you a look of perkier boobage
@ mamaspank ''I am waiting for boob jobs to get really cheap like plasma tvs!'' that's so cute ....
