Since 2007, we've been giving one dollar, one euro - whatever the local currency - of every ticket sold to Partners In Health and Kanpe. I think if you have a working band, that's about the easiest thing you can do - you just set it up and let it work!

It's important to understand the work that's being done, and to make sure it's actually helping. And sometimes, by working on it myself, I get a better grasp of the challenges and complexities of the task, and I'm able to talk about it better. That's why a balance of actual work and awareness is good, because they feed each other.
