And Getting Paid To Learn?

Now that sounds like a really interesting concept.  Knowledge should usually be its own reward, but the idea of making a living just for learning is pretty appealing to me.  I just wonder why I didn't come across this when I was in college. 

I think I'd go back to school in a heartbeat if somebody were to paying me for the experience.  What I seem to remember most about my college days was how much it seemed to keep costing me.
