bernan bernanke, do you do your own shopping at the grocery store asked by congressman paul, and why did he ask that? >> because the price of food has been increasing, and when the fed talks about the price of inflation they say they want the prices and the wages to increase no more than 2% per year, and food is increasing more than that, and the fed does not include food prices in the calculation of inflation, because the food prices fluctuate up and down quite a bit and the same reason they don't include gas prices in that measure, but what mr. paul is noting is that for ordinary americans buying food and gas living the ordinary lives, inflation can be a significant force than the numbers show, and challenging mr. bernanke saying that isn't inflation actually more of a problem than the fed is acknowledging. >> and bringing an ounce of silver to the hearing, what was that about? >> well, senator paul has a long history of arguing dr. paul, and that is that american currency should be exchanged for precious metals which it was for a long time and it was the called the gold standard w
