20 boxes meizitang been interusted in making a career out of any sport

Now this girl is looking to take the trials for long distance swimming for the 2008 olympics in colorado this summer,20 boxes meizitang, she made the trial cuts there the previous summer, and has plans to try again for the 2012 if she doesnt make it. Now my relationship with her pretty much aside, going to the olympics is something I can not accomplish with any of the previous sports Ive been involved with(minus wrestling,pastillas fruta planta usa, but I was never a good wrestler, Im built long and slender, most wrestlers are short and stocky, not an excuse though Im just not a good wrestler) However I feel that if she even goes to the Olympics and I do not get any competition on the international level (bearing in mind I have never, despite my potential in some, been interusted in making a career out of any sport) much less the olympics, that my status as an athlete when compared with my girlfriend would make me feel somewhat belittled. That being said my question is this, is it at all possible for my age if I were to start training now to make the 2012 games or would I be too old(for either the sport or the games as most athletes in those games tend to be of a younger persuasion)? Also, do my reasons for being motivated to do such seem wrong in anyway? I apologize for being long winded and hope that you can bring resolve to my conflict.
