I hope I'm posting this in the appropriate place, my sincere apologies if I'm not... I'm an old uni friend of Becca Stevenson, who I'm sure you all saw on Terry's Living With Alzheimer's documentary.
She's going to be running the London marathon in aid of the Alzheimer's Society - she's aiming for £2000 in sponsorship money and I'm running around the internet shamelessly publicising the fact in hope of inspiring people to donate! You can read more about it at the following link:
Thank you for your time, I'll let you get back to your regularly scheduled Pratchett chat - thanks in advance, every penny means the world to families fighting this awful disease
