I think most of us have seen the Matrix, where Keanu Reeves gets all the martial arts downloaded directly to his brain in a matter of seconds (or Trinity learns to fly a chopper). Imagine that you could, somehow, get the entire knowledge base/skills/physical ability of one thing in that same way. What would you choose to get, and why? I personally would love to get a lot of stuff, but the one thing I would get is an itimate knowledge of guitar - how to play in any style, how to toss in effects, etc. - and be able to play like Jimi, Steve, or Eddie.
