NO, you don't really notice that. Because it is in through your chest. I know that everyone has seen those pictures on those rocket slides where your face is pulled back in this fashion (pulls his cheeks back toward his ears) and you don't really feel that. You feel that in a T38 test figher, if you pull 6 G's. When you hit management cutoff, you have a fluid shift in your body and at that point your face becomes rounded out and puffed up and the lines in your face disappear and you look a few years younger for the time you're in space.
