Just watched this on BBC iplayer and I am in awe of Sir David. He has done so much with his life to help other mankind, other beings and the world. He is an exemplar of mankind.... 'And I think to myself, what a wonderful man!!!' I am inspired by Sir David, and his team to wake up and start living the best life I can. Thank you so much for being such a fantastic person, David and sharing your love of life and the world with us... May you have many more wonderful years to continue your brilliant work on planet earth. I thank you for your contribution. {??}
