So that little squiggly line, I'm just saying approximately negative 10% every 20 years. Negative 10% every 20 years. So if you go back 20 years, you should increase your percentage by 20%. So this should go up by, or you should increase your percentage by 10% I should say. So if we started at 41 or 42, once again, this is what we saw when we just eyeballed it. You should get to 51 or 52%. So my estimate of the percentage of American adults who smoked in 1945 would be 51 or 52%.
