Dear Family, Friends, Colleagues, I will shortly be celebrating (if that is the right word!) my 70th birthday. I'd like to use the occasion to remember my teacher and colleague, Arthur Wilson, who in later life suffered from Parkinson's. I'll be running round Richmond Park - a hilly 7.5mile circuit - to raise funds for Parkinson's UK. I'd be grateful a) if you would donate generously to a very good cause and b) if you would circulate and share this message. 

Many thanks! David
