<p>korzon, you allready got a lot of good reply's and you are applying now. Good Luck! I am also an 'older' (> 30) undergrad, now in my last year in college. Let me add a few comments not mentioned yet.
I got accepted into a school for 'non-traditional' students (General Studies of Columbia University). The school takes into account that most of its students are older, so they don't offer mandatory meal plans and undergrad dorm rooms (but grad student housing). The school also organizes social events and tries to create some sense of community, which means that it is easier to meet people of your own age.
You probably want that. Most 18/19 year students are nice and perfectly cool with the older students in class. I've worked with much younger people on class projects/presentations/homework and it went great. That being said, there is a great difference in experience and interests between 18 and 25 years old, I think much bigger than between 25 en 32. I don't go to keg parties, beer pong, studentbars, whatever. If you made $140K / year , you probably don't want to discuss how to spend the $137.53 budget in a 4 hour board meeting of some student club. Also, if you must or want to do an internship, you will have to search a bit harder for an opportunity where you can actually learn something in addition to your existing work experience.</p>
<p>Finally, I initially expected to be inspired by an extraordinary professor or to find a whole new interest through an awesome class. I took some classes outside my current fields of interests, but this did not happen (yet). Maybe, at some age one is too old to be influenced in such a profound way. </p>
<p>In conclusion, I do have the 'college experience' at a later age, however it differs slightly from the traditional 'college experience'. I also interupted my professional career for no other reason than to fill the 'hole' you were mentioning. I have not regret it for a second yet.</p>
