Look, for some people it is not easy to keep pace with the speed of development in any respect of life as science, medicine, technology. And now even accelerating wars. It is disturbing and troublesome. And when you get older, watch yourself, you would need a lot of energy and mental fitness to follow. Therefore, I think, take it easy. Not everybody could be a second Einstein. And I suppose you never wanted or even tried it. Go on with your life and have a drink on me and enjoy the last years of life in peace. Good luck
