I can think of at least 5 physicians and 2 med students here, off the top of my head, I know there is a another physician or two but their handles escape me at this time.
Personally, I took 2 years "off" between undergrad and med school (i worked) and believe it to be one of the best decisions I've ever made. I started med school at 24. The experience of medical school, like many things in life, may vary greatly from person to person, but the general gist is "it's fucking awful." this isn't to say it isn't worth it for the right person.
Feel free to PM me any specific questions you have.
