 So I'll start in terms of thinking about London in itself. London is a city that is cosmopolitan and it is diverse and probably one of the cities you go and meet every every nationality that you can. We've just come from Oxford with my kids and they were like oh this is different you know we definitely feel more at home here and and that's the opportunity it provides you and then when you think about science and the history behind science here when you you go down to the Natural History Museum you've got the exposure to things that you would never have exposure to in terms of science you've got great facilities and you've also got great teaching institutions and there's something about being engaged and being able to attend a youth forum in a place like the Royal Society of Geographical Society for example that history gives you that sense of oh yeah I can be part of history so it provides you that type of ownership and then the forum itself gives you the opportunity to take take part in that whole change and engage with people and engage in a in an area that you would not normally be able to get exposed so I really think exposure for me is what has built my career to where it is today and I embracing exposure is what as a global community we should be doing because we globalization is our language we're not living in silos and there's nothing inward about Ebola there's nothing inward about disease for example so the more we interact and the more global will become the easiest for us to address global issues
