Hi mr. Forbes. Thank you so much for taking the time to do this interview. I wonder if we could just start it really broad because your book obviously is about pressing topic of the day inflation and you define inflation a little bit differently in the book then its traditionally i think talked about here in america, and i wonder if you could just go through your definition and how how it differs from other definitions. Well really as we explained in the book, there are two kinds of inflation nonmonetary and monetary the nonmonetary kind which affects prices would be an event like such as a drought or the lockdowns that we had during covid or the war now undergoing in ukraine, which is affecting Food Supplies and Energy Supplies those kinds of events can send up prices. We underestimated for example with the covid lockdowns how intricate those supply chains were and have huge disruption sending up prices. Those are the non very kind of inflation though if they have authorities allow it
