I would like to return to the point at which I started with the Smoking/Non Smoking [sic] metaphor. In my life, there have been numerous occasions on which the metaphor could be applied. Some were very obvious, some less and some probably I was not even aware of, but the obvious ones were whether I would stay alive or not. There were several occasions when it could have gone into the 'not' direction, whether I would study or not study, whether I would become a teacher or not a teacher, whether I would be a botanist or some other scientist, whether I would defect or return to my home country, whether I would study H2 and non-H2, not H2, et cetera, et cetera. This session is in fact... is indeed the result of an incredible series of improbabilities, but I don't think it's anything... excuse me... I don't think it's anything unusual. Everybody's life is probably like that, and this is just that... I think that this is just one example of what many others have experienced. It is an example of a lottery that we are always playing the whole life and actually before we even become anything resembling human beings, the largest lottery actually occurs when one egg is selected to encounter another sperm... one sperm, and from that moment on until another lottery, the final lottery, our death, it ends the series of Smoking/Non Smoking [sic] events in our life.
