and what advice would you give to a billionaire in his 70s who's having trouble slowing down? my own feeling is that i'm in an extraordinary position and not to waste the position i find myself in. there are a lot of issues this world needs dealing with. you've got politicians who can do so much, but then there may be only two years maximum in a particular department before they've moved on to something else. i've had 55 years of experience as an entrepreneur and businessman and travelled the world and i think i'm in a position to help politicians and try to address some of the bigger issues of the world. and that's what i enjoy doing. and i'm not, i'm not going to sit back and not make the make the best of that position. i've heard that you're quite competitive. vaguely true? yeah, that's definitely true. are you? you're quite into chess, aren't you?
