at 32, i did. best decision of my life. and not because i had a horrible job. i had a great job working at a global investment company. i went from financial district to dorm-room in 3 weeks. i took nothing but math courses for 12 months. i'll likely do this again every ten years or so. i would highly, highly recommend it. and, i'm not going to give reasons why i recommend it because the value you get out of something like this is completely case by case. but, switching from "producer" to "learner" from time to time is an amazing experience.
