Walking for charity...

I found this article about charity walks interesting, because I've always found the idea of a charity walk baffling. I've been in one myself, last month, and it still puzzles me. Why do people contribute to charity walks when they don't give money to charities themselves? Is it the idea of people earning the money in some way, or - ? Is it because it's a combination of fun and self-sacrifice?

The thing is, it works. Obviously. Which is why the charities do it. I just don't quite get the psychology by which it's so effective.

The colour of time...

This delights me.
