I'm a big hand flaunter as well! It's just in my blood, I've always done it. It's like dancing but you're actually just talking :P I'm greek and you tend to see a lot of greeks speak with their hands. I agree with you though, it's very much a way to express the energy that you can't quite get out in words. I don't know what I'd do if I didn't have hands. It certainly is a big part of how I communicate!
