LoL!! Girl I'm 21 and my sister got one of those exersize balls for christmas and guess who was the first one bouncing up and down on it like a 5 year old? ME!! I still do it and she gets pissed at me cause I weigh more then her and she's all like, "YOU'LL POP IT!" but it's fun! Don't worry if you feel like a kid! Sometimes we all need to act a little immature or else life wouldn't be fun!
