Lots about my dad has changed in the last three years, due to his Alzheimer's, but his hands remain exactly the same as they have always been. He may not remember who I am but when I slip my hand into his, and feel his great paw, I am his daughter and he is my father and nothing, in essence, has changed. I am running the Vitality 10k to raise money for the wonderful place that he now calls home, named Nightingale House, part of the Nightingale Hammerson group. He is so beautifully cared for that it is a pleasure to do something to help those who help my dad. His favourite pastime is walking in the garden there looking up at the aeroplanes going in and out of Heathrow. He says things like: "That's a big one!" And I say: "Maybe it's going to New York, where all your cousins live." I will look up at the planes flying overhead, as I run the Vitality 10k through London, and think fond thoughts about my dad.
