Wind is my challenge; air, my favourite element. Breathing correctly, from the hara, is my current project. I tend to constrict and suspend breath when I'm anxious. I'm working on a more meditative mind, one that is more pranically connected.
And then, of course, there's the "gas" joke. When I break "Wind" it's all air, sometimes fizzle...hopefully not a squirt gun.
If I were a character in a sf/f novel, I'd call myself "Wind."
