Dianlya-
I have a good friend who is doing the exact same thing- going for med school. He said that older students commonly have a better chance of getting accepted because your "life experience" shows the schools that you understand hard work, know what you want, and have the discipline to get there. Best of luck!

And yes, it's a shame to spend your life hating what you do for a living, if you have a choice or a chance to change it. I need to shift my thinking into "Adventure Mode"!

thanks!
