I didn't write it down, but if you look at the AAMC stats "by age" you'll see which schools tend to accept the greatest # of students in your age bracket. Mine was 30-39. Another thing you might consider is adding not only DO schools but also the top 3 Caribbean schools (the ones that have US accreditation) and Atlantic Bridge Program (Ireland). Possibly also Australia--but I didn't research those cuz it's too far for me. I have some old less-than-ideal grades (over 10 years old), but an admissions director I heard give a talk said: if you have even a few C's on your record (no matter the reason or amount of time passed), you'll find it next to impossible to get into a US MD program, so you'll need to cast a wider net, especially if it's your third cycle or more. I hadn't realized that some ancient grades still tarnished my record to such an extent. But I did what he said and voila! now I'm into a great MD program in Ireland and on the WL for an IS school that I'll likely never get off of.
After this rollercoaster of a process, I'm not that bothered that I have to move across an ocean. I'll make it work. I'll be frugal. It'll be a fantastic adventure. I'm just glad this process is over and I'm going to be a doctor! So you have to ask yourself, how far are you willing to go to get off this ride and start getting your degree? What could you work with and what is a deal-breaker.. I hope that helps! I wish you all the luck in the world
EDIT: I should mention that the prehealth advisor from my old undergrad had the best of intentions and was very nice and supportive but played absolutely no part in helping me figure out what needed to be done to get in. He didn't even know about the ABP
