Most people go for the standard pre-med stuff, like an undergrad in biology or chemistry.
I had planned to go to chiropractic school at one time, but I went the chemistry route instead of biology... Didn't make it to chiropractic school, but the lab work sure comes in handy.
I must say that cooking nazi crank in my underground lab is much more fun than manipulating some fat, wrinkled old lady.
But, that's just me.
