Age?

To whom ever feels they can answer this.
I am aged 31 and have been well and truely bitten by the acting bug.
I have done about one years worth of night school training and have recently watched the NIDA Drama School documentary made a couple of years ago. The question I have is as a maturing person will my late attraction to thinking about acting as a potential career be a problem? Seeing mainly early to mid twenty something aged people seem to be those that attended NIDA in this doco.

Thanks for any feedback
