My recommendation is if you don't have to turn 30 don't do it.:+ Actually, all kidding aside, the 30's are wonderful and so is your body. Live in the moment and enjoy it because if you think about it 40 is just around the corner. Anyway, anything that is going to happen to your body doesn't magically happen overnight. I'm sure if you take care of your body it will take care of you!! Have an absolutley wonderful birthday!;-)
