As you can see, he's a hairy man. A very hairy man. And he has taken the incredibly heroic step of deciding to become a 'brave shaver' to raise funds for Macmillan and show support for those with cancer.
I'm so proud if him, and slightly terrified at the result, because Si wasn't content in raising a few bob to shave his head, oh no, he has also done a Kickstarter-esque fundraising scheme whereby the more money he raises the more body hair he loses! It is for a fantastic cause, and like he says, this is nothing compared to the bravery of people coping with cancer.
So if you have a few pennies lying around, why not help him along on his quest to become as smooth as a baby's bottom? All of the details can be found here at Si's page, and of course I will post the result next week. The Shave date is next Sunday (30th) so get on in there if you want to show your support!
