A wonderful human being has passed away. he touched the lives of many, and will further continue to do so with a marvellous legacy he has left behind.
I have been touched by this tragedy personally, the death of my best friend Frances with the same form of brain tumour Prof Chris O'brien had. It is painful to watch someone go through this...and I want to say to his family, stay strong, love each other and that Chris lives on in you all.
RIP Prof Chris O'brien.
