i am in the middle of my year off. i didn't do it so much to boost my ec's as because i just didn't want to go straight into school again. i was getting a bit tired of it at the end of my senior year. i've been working as a lab assistant at the medical center near where i live. it's good work, i've been able to save up some money for med school, i have nights and weekends free (no homework, no tests, yay!), and i've gotten to hang out with my friends and family for 6 months before packing it up for med school. i'd totally recommend a year off for anyone. i have friends who have worked and volunteered at a hospital, one who spent six weeks volunteering with a healthcare organization in peru, and one who is traveling in europe, getting odd jobs to pay for things. no matter what you do with your year, i think it will leave you refreshed and ready to jump into academia again (plus, it's a hell of a lot easier to complete secondaries and interviews when you don't have classwork to do)
