Sorry Resh, but according to science, you can't actively increase your reaction time. You can learn to predict very well, though.
Anyway, I guess I'd like to learn some sort of martial art. Capoeira and Sambo both peak my fancy, but I can't find any combat Sambo gyms anywhere near me. I've yet to look for one for Capoeira, but I imagine that if I want proper training in either art I might need to travel to their country of origin.
I'd also like to learn how to cook.
