Language would be a good one, took 2 years of german in high school and would love to just be dropped in germany for 1 year.
Carpentry is a good answer as well but sounds like it would take alot of work.
What about sports? I'm thinking that with an entire year to train I could probably take a crap ton of steriods and POSSIBLY get good enough to be a 5 Heart special teams player for the cats.
