I am on a mission to make 2017 my healthiest year yet, and I'm starting by taking part in the Edinburgh Marathon Festival. As I'm not completely daft, I've joined forces with some fabulous friends to run the Hairy Haggis relay course. I will be doing the shortest leg, at the slowest speed, but it will help me enormously to know that I'm raising money for a cause I hold very dear: preventing dementia. We are raising money to support the Centre for Dementia Prevention at the University of Edinburgh, which is leading global efforts to find new ways to prevent this awful condition. Thanks so much, Anna.
