Replying to Med School/CRNA Questions

Before anyone makes light of this not being the place to ask about being a Dr, I know, I feel stupid to but ya never know. My general plan is to head in the healthcare direction, anesthesia is very interesting to me however I think I'd rather do the CRNA route. One of my siblings is a PICU Nurse at a major hospital in Chicago, and as appealing as that sounds I don't know if I want that to be my career necessarily. I'm aware this is all over the place but to sum it up as simply as possible...is there a college major out there anyone did/knows of that I can do that allows me to have the option of going to Med School or doing a year + of ICU experience then doing my 3 years of CRNA School.
